A PS ee 2nd SN and MN — : “AUTOMATED SLIDING PIECE PROCESSING STATION AND A SAMPLE PROCESSING METHOD”
FIELD OF THE INVENTION The present invention relates generally to methods and apparatus for processing samples using thin films. More specifically, the invention relates to methods and apparatus for providing adjustable volume accommodation for processing samples. i ] BACKGROUND OF THE INVENTION | " A wide variety of techniques have been developed to prepare and analyze biological samples. Example techniques include microscope, DNA microarray analysis (eg, microarray analysis of protein and nucleic acid), and mass spectrometry methods. Samples are prepared for analysis by applying one or more liquids to samples If a sample is treated with multiple liquids, both the application and subsequent removal of each of the liquids can be important to produce suitable samples for analysis.
Microscopic slide pieces that support biological samples, for example tissue sections or cells, are generally treated with one or more pigments or reagents to add color and contrast to differentiate transparent or invisible cells or cell components. Samples can be prepared for analysis by manually immersing the parts - slides that support samples in containers of pigments or other reagents. This labor intensive process often results in inconsistent processing and transport of liquids between containers.
Transport of liquids leads to contamination and degradation of the liquids process. These types and manual processes often use excessive volumes of liquids resulting in relatively high processing costs, especially if the pigments or other reagents are expensive and prone to degradation due to transport.
Automated dip and dunk machines immerse samples in liquids similar to manual immersion techniques. These automated machines can process samples in batches—submerging shelves carrying microscopic sliders in open baths. Unfortunately, relatively high proportions of reagents are in bath vessels of automated immersion, submersion and soaking machines. Similar to manual processes, if liquids are expensive reagents, processing costs can be relatively high, especially if significant proportions of reagents are scrapped. Reagent bath containers can often be emptied because of contamination due to transport. Open containers can also be prone to evaporative losses, which can significantly alter the concentration of reagents, resulting in inconsistent processing. It can be difficult to process samples without producing significant volumes of waste that may require special handling and disposal.
Immunohistochemical staining and fluorescent in situ hybridization procedures are generally used to prepare specimens. The rate of immunohistochemical staining and fluorescent in situ hybridization of tissue fixed in section on a microscopic slide is limited by the rate at which molecules (e.g., conjugating biomolecules) can disperse into a fixed tissue from an aqueous solution brought into contact directly with the fabric section. Tissue is usually “fixed” immediately—after excision by applying a 10% solution of formaldehyde, which preserves tissue from autocatalytic destruction caused by cross-linking much of the protein via methylene bridges. This cross-linking fabric may present additional barriers to dispersion,
i 3 . oo — o including the lipid bilayer membranes that surround individual cells and organelles.
Conjugated biomolecules (antibodies or DNA probe molecules) can be relatively large, ranging in size from a few kilodaltons to many kilodaltons, which compels them to disperse slowly in solid tissue with typical periods for dispersion that can range from minutes to a few hours .
Typical incubation conditions are thirty minutes at 37 degrees Fahrenheit.
Ú “The rate of incubation is generally driven by a concentration gradient such that the rate of dispersion can be increased by increasing the concentration of conjugate in the reagent.
Unfortunately, conjugates are often very expensive, so increasing their concentration is wasteful and often uneconomical.
Additionally, the excessive proportion of conjugate that is conducted to the tissue, where high concentrations are used, is trapped in the tissue, is difficult to rinse, and causes high levels of non-specific background staining.
To reduce noise due to the level of non-specific background staining and to increase the specific staining signal, low concentrations of conjugate with long incubation times are generally used to allow the conjugate to bind only to specific sites.
Conventional histology staining instruments generally use relatively high volumes of reagents (100 pl) in a - —------ typically 300 ul pool of buffer.
This produces a very low concentration of the reagent in the pool that resides on the tissue.
Some conventional instruments mix the reagent by alternating tangential air jets in an overlying layer of oil that rotates and rotates in opposite motion when it comes in contact with the alternating air jets, thus transmitting motion into the tangential water puddle.
This mixing is low and not particularly vigorous and creates significant evaporation losses.
Large volumes of rinse liquid are used to physically displace large pools of low reagent concentration that are covered with oil. This rinsing procedure produces large volumes of waste liquid which can be hazardous waste, and can physically break the fabric from the action of vigorous washing.
DESCRIPTION OF THE INVENTION At least some embodiments are directed to a method that brings a sample into contact with a liquid by moving a curved surface moistened by a liquid in proximity to the biological sample. The distance separating the wetted curved surface and the biological sample is sufficient to form a meniscus layer of liquid between the curved surface and the slide. The meniscus layer comes into contact with at least part of the biological sample. The meniscus layer can be a relatively thin film that is accommodated in the gap. The substrate is moved to different configurations to accommodate different volumes of fluid forming the meniscus layer. Capillary action to move the meniscus layer may include, without limitation, layer movement due to the phenomenon: of liquid spontaneously sliding through the gap between the curved wetted surface and a slide due to adhesive forces, cohesive forces and/or surface tension .

DESCRIPTION OF EMBODIMENTS OF THE INVENTION Figure 1 shows a first substrate 80, a second substrate 82, and a substance 86 between the first and second substrates 80, 82. The first and second substrates 80, 82 can be moved together to handle the substance. 86, such as a processing liquid. Handling substance 86 may include agitating substance 86, spreading substance 86 along an upper surface 90 of the first substrate 80, moving substance 86, or otherwise manipulating substance 86 to process a biological sample 88 on the upper surface. 90.
Protocols can be performed using enhanced net volumes to minimize or avoid problems with excessive volume consumption, which includes high processing costs and scrap management. In some embodiments, an interval 91 may have
- 24 a variable height, e.g. a height that varies along the length and/or width of the gap formed by the first and second substrates 80, 82 to enable variable volume processing.
In variable volume processing, improved volumes of liquids can be used to process to increase efficiency and reduce scrap volume and cost when compared to fixed volume processing (i.e. processing that uses only a constant volume of liquid. for each liquid application). Reductions may be based on reduction | volume of liquid consumed, as well as the reduction of system costs by reducing or avoiding relatively high costs associated with greater consumption of liquid volume, which includes manufacturing costs, packaging costs, transportation costs, consumer workflow (eg, administration cost for inbound inventory as well as outbound scrap management), and higher fluidic management costs.
Excess fluid volumes can also lead to excessive waste or malfunctions (eg, clogging, leakage, or the like) of fluidic components and may require frequent recalibration of equipment.
Substrates 80, 82 can be used to efficiently process sample 88 while avoiding or limiting at least some of the problems associated with larger volumes of liquid. o oe Gap 91 can accommodate a wide range of liquid volumes, even without moving substrates 80, 82. In some embodiments, slot 91 can accommodate liquid volumes greater than about 10 microliters.
In some embodiments, the slot 91 can accommodate liquid volumes in a range from about 10 microliters to about 200 microliters.
The height profile of the gap 91 can vary based on the volume of liquid or the properties to be used.
To treat sample 88 with a volume
- 25 :
large amount of liquid, the gap size 91 can be increased to avoid overfilling.
In some embodiments, overfilling occurs when the volume of liquid dispensed is greater than the volume of the gap.
91 (e.g. the volume between the first and second substrates 80, 82). THE
—overfilling can lead to undesired conditions, which include liquid depression and/or fluid drainage, especially if substrates 80, 82 are in a vertical orientation.
If smaller or smaller volumes of liquid are to be dispensed, the gap size 91 can be decreased to avoid underfilling.
Underfilling can lead to improper contact between liquid 86 and sample 88 and occlusions.
Figure 1 shows the ends 94a, 94b (collectively "94") of the gap 91 that can be filled with liquid 86 by reducing the height gap, changing the height profile of the gap, and/or adding liquid. in the range 91. Advantageously, a significant volume of liquid can be conveniently added without overfilling.
By preventing overfilling and underfilling, different types of fluidic failure modes (eg, reagent performance degradation), reagent scrap, or the like can be avoided or limited.
Processing protocols may require different volumes of liquid in order to satisfy various processing criteria (eg chemical requirements, absorption requirements, solubility limitations, viscosity or the like). If sample 88 is a paraffin-embedded specimen, a relatively small volume of dewaxing solution (e.g., 12 microliters of xylene) can be delivered in range 91. Substrate 82 is used to apply liquid to sample 88. For example , substrate 82 can be rolled (e.g., rolled along an imaginary plane spaced from top surface 90, rolled along top surface 90, rolled sideways, rolled
- 26 : oo longitudinally, or the like) or otherwise manipulated (e.g., rotated, translated, or both) to apply liquid 86. A surface facing specimen 92 of substrate 82 may be used to manipulate reagent volume . After dewaxing, a relatively large volume of reagent can be delivered in the 91 range. For example, a volume of about 80 microliters to about 120 microliters of dye can be delivered to the o. interval 91. Dye is delivered to sample 88 and then subsequently removed. The substrates 88, 82 may then cooperate to hold different amounts of fluid for rinsing, staining, incubating, or the like.
The slot 91 of Figure 1 may have a minimum holding capacity of about 5 microliters (shown in solid line in Figure 1) and a maximum holding capacity of about at least 5 microliters, 50 microliters, 100 microliters, or 200 microliters (shown in the dashed line in —Figure 1). Other minimum and maximum holding capacities are possible if required or desired. The minimum holding capacity is the smallest volume of liquid that can be contained in the 91 gap and effectively applied to the 88 sample. The maximum holding capacity is the largest volume of liquid that can be contained in the 91 gap without —overfilling. The variable height gap 91 can accommodate a wider range of volumes of liquid than a uniform height gap, as the narrowed region of the gap 91 can accommodate a small volume of liquid, while the widened gap end 94 can accommodate a volume large amount of liquid. The extended 94 range end too — can provide convenient access to deliver liquid to the 91 range.
Second substrate 82 can move liquid 86 through capillary action. When the height of gap 91 is small enough, gap 91 is a capillary gap that can be maintained without regard to
- 27 presence or absence of liquid. A liquid with low viscosity, such as water, can be retained by capillary action in the 91 range. Substances with high viscosity can also be retained in the 91 range if desired. A portion of the capillary gap 91 may be narrower and have greater capillarity than a portion of the different capillary gap 91. A thin film of liquid 86 may tend to flow into the narrowed portion of the gap.
91. The separation between substrates 80, 82 at any given location on surfaces 90, 92 may vary over time. Figure 1 shows the substrate as a whole 82 spaced apart from the substrate 80. If the substrate 82 physically contacts the top surface 90, liquid 86 may tend to flow along the contact interface. Even though the substrate as a whole 82 is distanced from the substrate 80, the substrates 80, 82 can effectively enclose the liquid 86.
In one embodiment, the gap forming elements may be outwardly protruding recesses positioned in the substrate 82. The gap forming elements may also include, without limitation, one or more positioners, rails, spacers, or other structural features capable of serving as spacers. . In some embodiments, the substrate 82 includes one or more tracks (e.g., straight tracks, arched tracks, or the like) configured to abut against the top surface 90. In still other embodiments, the gap-forming elements may be separate components. positionable between substrates 80, 82, or any other suitable location. Gap forming elements may also be adjustable in their dimensions, positions or orientations to adjust the gap between substrates 80, 82. To move liquid 86 across top surface 90, a first end 96 of substrate 82 in Figure 1 may be moved toward substrate 80 until liquid 86 is in the position shown in
Figure 2. Liquid 86 can also be moved to an opposing second end 98 of substrate 82 by narrowing the portion of gap 91 formed by second end 98, as shown in Figure 3. In this manner, ends 96, 98 can be —alternatively raised and lowered to move liquid 86 through, for example, capillary action or any kind of mobility force. Alternatively, substrate 80 may be moved relative to a stationary substrate 82 to similarly move liquid 86. Figure 4 shows gap 91 which has an approximately uniform height such that liquid 86 fills a substantial volume of gap 91. The volume of range 91 is the volume directly.
between the first and second substrates 80, 82. The range of the holding capacities of the gap 91 of Figure 4 is narrower than the range of the holding capacities of the variable height gap 91 in Figure 1. For example, the range 91 of Figure 4 can have a nominal gap height of about 0.008 cm, a width of about 2.5 cm, and a length of about 5 cm to effectively accommodate: 0.008 cm x 2.5 cm x 5 cm = 0.1 | cm = 100 microliters of liquid volume. An excess or deficiency of about 1 to 10 microlittos can result in overfilling or —underfilling. The difference between the minimum holding capacity and the maximum holding capacity of the variable height range 91 of Figure 1 may be at least about 25 microliters, 50 microliters, 100 microliters, or 150 microliters, or ranges covering such volumes of liquid. Substrate 82 in the curved configuration (see Figure 1)—can expose a relatively large surface area of liquid 86 to the surrounding environment. To reduce evaporative losses, the radius of curvature of the substrate 82 can be increased to reduce the exposed surface area of the liquid 86. The substrate 82 in Figure 4 is especially
- 29 i — — ——. ——. ——+ — To — | well suited to minimize or substantially eliminate losses by | evaporation and/or significant sample losses.
By controlling evaporation and sample losses, substrates 80, 82 can be used to perform different types of incubation procedures, as well as other low evaporation procedures.
As used herein, the term “substrate” is | a broad term and includes, but is not limited to, a coating, a part ! slide, a coverslip, a strip of material, a plate, a membrane, a = film (e.g. a coating), a tile, a carrier capable of carrying one or more samples, or the like.
Substrates can be substantially rigid, semi-malleable, and/or malleable.
In some embodiments, the substrate 80 is a microscope slide.
A substrate can also be part of another component.
For example, a stage or handle may have an outer surface that forms a substrate.
Dimensions, properties (which include mechanical properties, chemical properties, surface properties, and/or optical properties) and substrate configurations can be selected based on the processing protocol and subsequent analyzes to be performed.
In some embodiments, a substrate may be a substrate—flat or substantially flat. "Substantially flat substrate" refers, without limitation, to any object that has at least one substantially flat surface, but more typically any object that has two substantially flat surfaces on opposite sides of the object, and even more typically to any object that has substantially flat opposing surfaces whose opposing surfaces are generally equal in size but larger than any other surfaces on the object.
A substantially flat substrate may comprise any suitable material, including plastics, rubber, ceramics, glass, silicon, semiconductor materials,
. 30 metals, combinations thereof, or the like. Non-limiting examples of substantially flat substrates include flat covers, slide pieces (both 2.54 cm x 7.62 cm (1 inch x 3 inch) microscope slide pieces and 25 mm x 75 mm microscope slide pieces), — SELDI and MALDI chips, silicon wafers, or other generally flat objects with at least one substantially flat surface.
. Substrate 82 can be semi-malleable, malleable, or rigid for the purpose of assuming or maintaining a wide range of configurations. Figures 1 through 3 show substrate 82 in a single arc configuration. Simple arcs include arcs that have generally uniform curvatures. The bending radius of single bows can be about 1.27 cm (0.5 inch), 2.54 cm (1 inch), 12.7 cm (5 inches), 50.8 cm (20 inches), 76.2 cm (30 inches), 88.9 cm (35 inches), 101.6 cm (40 inches), 114.3 cm (45 inches), or ranges covering such | 15 bending radii. Other rays are also possible. In some embodiments, the radius of curvature is in a range of about 12.7 centimeters (5 inches) to about 101.6 centimeters (40 inches). Such a substrate may be well suited for applying a liquid by using a rolling or rocking motion while effectively managing evaporative losses, if any, and controlling fluid movement. In other embodiments, the substrate 82 may assume a complex arc configuration or a composite arc configuration. If the substrate 82 is in a complex arc configuration, at least a portion of the substrate 82 may have a variable curvature. If the substrate 82 is in a composite arc configuration, a portion of the substrate 82 can be a simple arc and another portion of the substrate 82 can be a complex arc.
Multiple related specimens can be treated on the top surface 90 using a single substrate. The specimens can
: 31 be treated concurrently or sequentially with the same fluid. Figure 5 shows the liquid 86 that treats the sample 88a (shown in the dashed line). Liquid 86 is then moved to another sample 88b. Figure 6 shows the liquid 86 that treats the sample 88b (shown in the dashed line). In this manner, liquid 86 can be moved along substrate 80 for a number of related specimens.
In some protocols, both related specimens 88a, 88b may be rinsed with an appropriate solution, such as a non-volatile transfer fluid or other suitable fluid to prevent drying.
After stabilizing specimens 88a, 88b, substrate 82 can form a narrowed section of gap 91 near sample 88a. A reagent (e.g., a dye) can be delivered in slot 91. Substrate 82 can be moved to translate a layer of liquid 86 between specimens 88a, 88b. The liquid 86 used to process the sample 88a can be removed through a waste port 104 (shown in the dashed line). A refuse port 106 (shown in the dashed line) can be used to remove liquid used to process sample 88b. In this manner, substrate 82 can be used to individually treat specimens 88a, 88b at the opposing ends of substrate 80, as well as any other specimens, or at any other suitable location along substrate 80.
Figure 7 shows a part processing apparatus - . slide 100 which includes a positioning mechanism 99, a base unit 110, and a refuse remover 130. The base unit 110 carries an opposing substrate 140 used to apply a processing liquid to one or more specimens carried by a slider. microscopic 120. The liquid can balance and remain in a static condition for a desired period of time, even for long periods of time.

The pivot mechanism 196 defines an axis of rotation 193 around which the substrate 140 rotates. To roll the substrate 140 from the position shown in Figure 8 to the position shown in Figure 9, the actuator 194 can extend and the pivot mechanism 196 can rotate.
Processing liquid 160 can be effectively applied to sample 187 to minimize or limit the cost of processing liquid(s) and to minimize or limit the amount of waste liquid produced. Substrate 140 may be manipulated (e.g., translated, rotated, vibrated, or combinations thereof) to move liquid 160. To agitate liquid 160, substrate 140 may be rolled along slide 120. substrate 140 in a curved configuration may rotate due to physical contact with slider 120. In other embodiments, substrate 140 may run along slider 120.
Liquid 160 may be moved along slider 120 eee due to different forces, such as gravity, capillary forces, and/or a change in pressure (e.g., reduced pressure such as a vacuum) within a range 170. Substrate 140 in Figure 8 is suitable for moving liquid 160 through sample 187 by, for example, scrolling back and forth across sample 187. Substrate 140 may assume a generally flat configuration to form a thin film across sample 187 to, for example, incubate sample 187.

Referring to Figure 8, an actuation assembly 180 of base unit 110 includes actuators 182a to e (collectively "182") that can be selectively extended and retracted to move substrate 140. Actuation assembly 180 may include, without limitation, one or more drives (e.g. linear drives, reciprocating drives, or the like), motors (e.g. stepper motors, drive motors, or the like), solenoids, piston assemblies, gear trains, combinations thereof, or others electronically, mechanically, hydraulically, or pneumatically driven components capable of moving substrate 140.

A plurality of gap forming elements 183a to | (collectively "183") is positioned along the bottom surface 200 of substrate 140. Gap forming elements 183 may maintain spaced surface 200 of slide 120 to maintain a capillary gap. The heights of the gap forming elements 183 may be equal to or greater than a thickness of the sample 187. If the substrate 140 is pressed against the slider 120, the gap forming members 183 may surround the sample 187 and maintain a suitable gap to maintain a thin film. In certain embodiments, the gap forming elements 183 may serve to limit the compression of the sample 187. The gap forming elements 183 may have heights that are approximately equal to or slightly less than a thickness of the sample 187 so that the sample 187 can be compressed without being damaged.
Substrate 140 may be made, in whole or in part, of one or more polymers, plastics, composites, glass, combinations thereof, or other suitable materials which may be generally rigid, semi-rigid, and/or malleable. For example, substrate 140 can be a rigid glass plate. If substrate 140 is flexible, substrate 140 may be made of one or more polymers, such as polyester, polyethylene terephthalate, polypropylene, rubber, polyvinylidene fluoride, polytetrafluoroethylene, or combinations thereof. The composition of substrate 140 can be selected based on desired characteristics, which include, without limitation, surface energy, flexibility, wettability, chemical compatibility, adhesion characteristics, or the like. In some embodiments, the slide 120 and the
Substrate 140 may be made of a hydrophobic material to ensure sufficient containment of liquid 160. Scrap remover 130 includes a pressurizing device 220 and a receiving line 230 extending from pressurizing device 220. 220 can extract liquid 160 in receiving line 230.

An inlet 185 of line 230 — may include one or more openings, or other types of features, through which liquids can flow.
Processing apparatus 100 may have different modes of operation.
In some embodiments, the apparatus 100 has a static and
' 39 a dynamic mode. In dynamic mode, substrate 140 can be moved to agitate liquid 160. For example, a rolling motion can generally provide even coverage of liquid across sample 187. Substrate 140 can be rolled back and forth across the sample 187 numerous times. If the liquid 160 has a relatively low viscosity, the substrate 140 can be moved at a relatively high speed. If the liquid 160 has a relatively high viscosity, the substrate 140 can be moved at a relatively low speed. The speed of the substrate 140 can be increased or decreased to increase or decrease the agitation of the liquid 160. Agitation can affect absorption rates. of fluid, settling of constituents in liquid 160, mixing of constituents, combinations thereof, or the like. Processing apparatus 100 may also be used to perform mixing on the slide to sequentially or simultaneously mix the discharged fluids. For example, a first fluid aliquot 160 can be dropped into the slide
120. An aliquot of another fluid can be dropped onto substrate 140 and mixed using fluid 160. Countless fluids can be dropped to produce a wide range of mixtures. In some modes of operation, substrate 140 may be used to agitate fluid 160. After agitating fluid 160, another fluid may be disposed between slider 120 and substrate 140. Substrate 140 then agitates both fluids to produce a mixture. ' Alternatively, the reagents can be mixed outside the slide and discarded into the slide in a pre-mixed state. In static mode, substrate 140 may be used to minimize, limit, or substantially prevent movement of liquid 160. Substrate 140 may be held stationary with respect to slider 120 and may assume a generally flat configuration, or a with a relatively large radius of curvature, to avoid evaporation losses o - . 40 excessive. Apparatus 100 may be in a static mode to perform incubation or other processes may require a significant amount of time. Advantageously, a wide range of different volumes of liquid 160 can be used to provide dynamic processing and static processing, which includes high volumes of fluid greater than about 100 µl, and low volumes of fluid, such as fluid volumes smaller than about 100 µl. of 100 ul. Other volumes of fluid are also possible, if necessary or desired.
Referring to Figure 10, the substrate 140 is in the flat configuration, which can be used for static processing. Static processing may include, without limitation, incubation, thermal processing, or other types of processes that involve a minimal amount of liquid movement. .
A protocol may include using substrate 140 to form thick layers, thin films, meniscus layers, or the like. To form thick layers of liquid, substrate 140 can be separated from slide 120 and sample 187, as shown in Figure 8. Such embodiments are suitable for treating sample 187 using a high viscosity substance such as a gel. If the gel is inadvertently drained, the gap forming elements 183 can protect the sample 187 from: - —------unwanted compression and associated damage. To form a thin film, gap forming elements 183 can be pressed against slider 120. If substrate 140 is in a curved configuration, a meniscus layer can be formed.
Figures 10 to 13 show a method of processing a sample. Liquid 160 can be moved towards a region 247 of the gap 170 through capillary action as an opposing region 249 of the
. 41 range 170 widens. Figure 11 shows a bolus of liquid 160 in region 247 of substrate 140. Bolus of liquid 160 can be reapplied to sample 187 by enlarging region 247 and narrowing region 249. As region 249 narrows, liquid 160 accumulates at the end. 142. Figure 12 shows the liquid 160 accumulated in the narrow region 249. The refuse remover 130 can | then aspirate the fluid bolus 160. | To additionally accumulate liquid 160 and/or to reduce the | capillary forces, the end 142 of the substrate 140 can be moved away from the slider 120. As the angled bottom surface 200 in the | 10 is rotated away from slider 120, liquid 160 is urged closer to opening 215 of inlet 185. Substrate 140 can be moved to a generally parallel orientation with slider 120 to move liquid 160 o as close as possible to the scrap remover
130. Scrap remover 130 can then draw liquid 160 out of gap 170.
The method of Figures 10 to 13 can be employed to accumulate liquid in a wide range of locations, including the corners, sides, and/or ends of substrate 140 and/or slider 120. The position of scrap remover 130 can be selected. based on the desired location of scrap accumulation.
Processing apparatus 100 can process sliders in different orientations, which include a generally vertical orientation, horizontal orientation, slanted orientation, or the like. Figures 14 and 15 show slider 120 in a generally vertical orientation to promote movement of a fluidizable substance 213 along slider 120. End 142 of substrate 140 of Figure 14 extends away from slider 120 to form an enlarged gap 209. A dispenser assembly 208 may emit substance 213 through the relatively large gap 209 so that substance 213 begins to collect in a narrow region 212 of a capillary gap 214. The dispenser assembly 208 may be a pipette that dispenses substance 213 comprising premixed reagent. The volume of discarded substance 213 can be from about 75 microliters to about 500 microliters. Substrate 140 can be rolled back and forth to move substance 213 that fills the narrow region 212, while gravity helps to pull substance 213 downwards.
Figure 15 shows the gap 214 filled with the substance
213. The lower end 192 of substrate 140 can be moved toward slider 120 to further propagate substance 213. Slider 120 and substrate 140 can be rotated together counterclockwise (indicated by arrow 220 in Figure 14) or clockwise (indicated by an arrow 224). To perform an incubation process, the slider 120 can be moved to a generally horizontal orientation, and the substrate 140 can assume a substantially flat configuration. To treat the sample 187 with another fluid, the slide 120 can be moved to a | tilted or vertical orientation. The orientation of the slide 120 can be selected based on the processing to be performed, such as immunohistochemical processes (eg, dewaxing, antigen retrieval, and detection (cell conditioning)). For dewaxing using the aqueous process described in US Patent No. 6,544,798B1 (aqueous dewaxing using heat), incorporated herein by reference, heat may be supplied to heat either substance 213 (e.g., an aqueous solution), which bathes the biological sample 187 above the melting point of paraffin, or a heater built into the substrate 140 could directly heat the sample 187. The heat may be sufficient to heat the sample 187 above the melting point of
. 43 paraffin to release the paraffin into the immiscible aqueous phase where it is then removed.
One or more heaters 211 may be activated to heat the substrate 140. Additionally or alternatively, a heater 217 may contact and heat the backside of the slider 120. The slider 120 may be in the angled orientation to promote paraffin removal or any solvents such as xylene or limonene.
In some protocols, the volume of captive fluid is kept in a range of about 15 microliters to “about 25 microliters.
In certain protocols, the volume of fluid is about 15 — microliters.
Countless times during processing, a volume of reagent, reagent buffer, or water may be pipetted onto the slide 120 to restore fluid volume. . Processing apparatus 100 can perform mixing on the slide.
A first reagent can be discarded.
Substrate 140 is rolled to absorb reagent between slide 120 and substrate 140. Substrate 140 is then positioned to allow access for pipette dispensing while maintaining fluid capture.
Another reagent is discarded.
Substrate 140 is then rolled longitudinally, laterally, or both to mix the reactants through consecutive rolling cycles.
Incubation can be performed if needed or desired.
Figures 16 and 17 show a slider processing station 300 that includes a roller unit 310 and a slider positioning device 316. The slider positioning device 316 includes a slider holding device 330 that holds a microscopic slider 340 and an actuator 320 to activate the slider retaining device 330 (a gripping device is shown, but other embodiments that retain the slider will be apparent to those skilled in the art, such as through friction fit of hair least a portion of the slider within a cavity or clips or
- 44 preachers, for example). Slider 340 extends from slider retainer 330 in an overhung manner and rests on roller unit 310. Actuator 320 is mechanically coupled to roller unit 310 and carries a slider retainer 330 , Slider 340 and a substrate 350 (illustrated in the form of a cap) can treat a specimen (shown in dashed line 260 in Figure 17) on a bottom surface of slider 340. Slider 340 can move along of the cap 350 in a scroll drive to stir the liquid.
A platinum assembly 361 of Figure 18 includes the cover 350 and a base 360. The base 360 includes a network of channels 370 through which a vacuum can be applied to secure the cover 350 with respect to the face 359 of the base 360. cap 350 overlaps base 360, a waste port 374 of cap 350 is aligned with an inlet 380 of a waste passageway of base 360.
The network of channels 370 includes an outer channel 394 that extends along the periphery of the base 360. An inner channel 396 extends between opposing sections 397, 398 of the outer channel 394. The outer channel 394 can hold the outer periphery of the cap 350 relative to face 359, and inner channel 396 can hold a central region of cap 350 relative to face
359. Other channel configurations are also possible.
..-- minis The pattern, number, dimensions (eg width, depth, or the like) and configurations (eg U-shape, V-shape, or similar) of the channels can be selected based on the desired interaction between cap 350 and base 360. Figure 19 shows an outer channel 400 and an inner transverse channel 402 extending between the longitudinal sides 404, 406 of the channel 400. The inner channel 402 is generally midway between a scrap 409 and a bottom section 407 of the
. | ! 45 outer channel 400. A through hole 408 can connect the outer channel 400 to a fluid line so that a vacuum can be applied through the through hole 408. Figure 20 shows a single continuous outer channel 412. Figure 21 shows a network of channels that includes an outer channel 416 and a channel 420 that connects a flow inhibitor 418 to the outer channel 416. A vacuum applied through a through-hole 422 can either hold a lid relative to a face 423 or can vacuum the flow inhibitor 418. Figure 22 shows a base 442 with a network of channels 429 that includes an outer channel 430 and an inner channel 432. The inner channel 432 extends longitudinally along a main body 440 of the base 442. end 446 of the inner channel 432 is spaced from a flow inhibitor 448 so as to prevent fluid collected in the flow inhibitor 448 from entering the network of channels 429. The inner channel 432 is especially suitable for holding the central region of a too pa securely with respect to the main body 440.
Additionally or alternatively, the bases may include one or more clamps, adhesive layers, mechanical fasteners, or the like capable of selectively holding and releasing the cap 350. In some embodiments, the base 360 of Figures 16 to 18 is an electrostatic mandrel. In still other embodiments, base 360 may include one or more receivers (e.g., holes, slots, or the like). The cover 350 may have protrusions or other features that are received by those receivers. Referring to Figures 23 to 25, cap 350 includes a first row of gap forming elements 450 and a second row of gap forming elements 452. Region 453 is between the two rows of gap forming elements 450, 452. Edges 454 , 456 can be dimensioned with respect to the slide to provide the desired liquid application region 453 (e.g., the entire top surface of the lid 350, the largest
- 46 part of the upper surface of the cap 350, the region between elements 450, 452, or the like). In certain embodiments, substantially the entire top surface of cap 350 comes in contact with fluid that is applied to the specimen. As such, most of the space between the cap 350 and the slider can be filled with liquid. In some embodiments, the specimen may be positioned between the rows of elements 450, 452. A liquid disposed of by flowing through the elements 450, 452 towards the "edges 454, 456 of the lid 350." In some embodiments, the forming elements of range 450, 452 can help process a specimen with a desired amount of fluid (e.g., a minimal amount of fluid). Gap forming elements 450, 452 may also be spaced apart to prevent, limit, or substantially prevent absorption between adjacent elements. If a liquid reaches one of the gap forming elements 450, 452, the liquid can reside at the contact interface between that gap member and the slider 340 without flowing into an adjacent gap member. Gap forming elements 450, 452 are spaced from edges 454, 456 of cap 350 to keep liquid close to liquid application region 453. Additionally, liquid is kept far enough from edges 454, 456 to prevent spillage. leakage from below the slide even if another object comes into contact with the - - edges 454, 456.
The rows of gap forming elements 450, 452 extend longitudinally along a length of the cap 350.
Opposing gap-forming elements of each row 450, 452 are generally laterally aligned so that the slider 340 (see Figure 16) can contact laterally aligned elements 450,
452. As slider 340 is moved along cover 350, slider
. 47 slide 340 is successively brought into contact with laterally aligned gap forming elements 450, 452. Each of the rows 450, 452 may be generally similar to one another. Accordingly, the description of one of the rows 450, 452 applies equally to the other, unless otherwise noted.
Row 450 can include from about 5 gap forming elements to about 60 gap forming elements with an average distance between adjacent gap forming elements in a range of about 1.27 mm (0.05 inches) to about 15.24 mm (0.6 inch). In some embodiments, including the illustrated embodiment of Figures 23 and 24, the row 450 includes 19 gap forming elements that project outwardly from the surface 460, illustrated as a surface-facing specimen. In other embodiments, the row 450 includes from about 10 gap forming elements to about 40 gap forming elements. As viewed from above (see Figure 24), row 450 has a generally linear configuration. In other embodiments, the row 450 has a zigzag configuration, winding configuration, or any other configuration or pattern.
The gap forming elements 450 may be evenly or non-uniformly spaced from one another and may form an approximately straight row or may be staggered. The distance between adjacent gap-forming elements 450 may be greater than the heights of the gap-forming elements and/or less than a thickness t (see Figure 26) of a body 459 of cover 350. Other spacings—are also possible , if necessary or desired. A width W of cap 350 can be in a range of about 15.24 mm (0.6 inch) to about 38 µm. mm (1.5 inches). Other widths are also possible. In some embodiments, the width W is equal to or greater than a part width.
: 48 slide 340. If fluid flows out beyond slider 340, fluid can thereby remain in cap 350. Referring to Figure 24, the distance D between rows 450, 452 can be selected with based on specimen dimensions and slider dimensions 340. In some embodiments, distance D is in a range of about 6.35 mm (0.25 inch) to about 25 mm (1 inch). If slider 340 is a standard microscopic slider, the distance D may be less than about 12.7 mm (0.5 inch). Figure 26 shows one of the gap forming elements
450. The height H of the gap element 450 can be selected based on the thickness of the specimen to be processed. Gap element 450 may have a height H equal to or less than about 0.38 mm (0.015 inch) if the specimen is a tissue section with a thickness that is less than about 0.38 mm (0.015 inch). In some embodiments, the height H is in a range of about 0.025 mm (0.001 inch) to about 0.127 mm (0.005 inch). In certain embodiments, the height H is about 0.076 mm (0.003 inch) for processing thin fabric sections with a thickness of less than about 30 microns, 20 microns, or 10 microns. A ratio of the height H of the gap forming elements 450 to the radius of curvature -R of the main body 459 can be greater than about 0.0001. For example, the ratio of height H to radius of curvature R can be in a range of about 0.0001 to about 0.0075. The pattern, number, dimensions, and configurations of gap forming elements can be selected based on the desired interaction between the specimen and the liquid. If the cap 350 includes a field of gap forming elements, the gap forming elements may be uniformly or non-uniformly distributed across the cap 350 to form different patterns which may include, without limitation, one or more
: 49 plus rows, layouts, geometric shapes, or the like. Gap element 450 may be a partially spherical cavity, partially elliptical cavity, or the like. The illustrated member 450 is a substantially partially spherical cavity especially suited for sliding contact of the slider 340 without damaging (e.g., damage or scratching) the slider 340. If the specimen is large enough or moves toward one side of the microscopic slide piece 340, the specimen may slide over the spherical cavity 450 without damaging or dislodging the specimen with respect to the slider 340. In other embodiments, the gap member 450 may be in the form of a polyhedral protrusion, a conical protrusion, a frustoconical protrusion, or other combination of polygonal and arcuate shapes.
The main body 459 of Figure 25 is in the shape of a simple arc with a radius of curvature R in a range of about 5 in (2 inches) to about 76 cm (30 inches). In some embodiments, the radius of curvature R is about 38 cm (15 inches) or about 74 cm (20 inches). Such embodiments are suitable for mixing reagents in the slide. The radius of curvature R can be selected based on the number of specimens to be processed, amount of fluid agitation, properties of processing liquids, the height of gap forming elements 450, 452, and the like. In other embodiments, the . 350 is in the form of a complex arc (eg, an elliptical arc), compound arc, or the like. In still other embodiments, the cap 350 may be substantially flat.
Cap 350 may be made, in whole or in part, from polymers, plastics, elastomers, composites, ceramics, glass, or metals, as well as any other material that is chemically compatible with the specimen and processing fluids. Exemplary plastics include, without limitation,
: 50 polyethylene (eg, high density polyethylene, linear low density polyethylene, blends, or the like), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), perfluoroalkoxy (PFA), or combinations thereof. If the cap 350 is disposable, the cap 350 may be made, in whole or in part, of a relatively inexpensive material. If the cover 350 is rigid, it may be made, in whole or in part, of polycarbonate, urethane, polyester, a metal coated plate, or the like. The cover 350 may have a | or more pins, pegs, protrusions, receivers, or other features used | to hold the cover 350.
Cap 350 may be formed through injection molding processes, compression molding processes, extrusion process, machining process, or combinations thereof. For example, an injection molding process can be used to manufacture main body 459 and gap forming elements 450, 452. Waste port 374 can then be machined into main body 440. In other embodiments, cover 350 can be a monolayer, multimembrane, film, or coating membrane. An underlying component may have one or more gap-forming elements to which the cap 350 can conform to form corresponding gap-forming elements (e.g., bulges, protrusions, or the like). For example, gap forming elements may be positioned on face 359 of base 360 of Figure 18. When cover 350 overlaps base 360, cover 350 may conform to gap forming elements. As such, cap 350 may be permissive to gap forming elements.
If the cap 350 is in the form of a film, the film may include an adhesive layer. The adhesive layer may comprise, without limitation, one or more pressure sensitive adhesives, adhesive gels, binding agents or the like. In some realizations, the film is a blade that is dispensed with.
- 51 of a roll. Each slider can be processed with a different blade section to prevent unwanted contamination. In other embodiments, individual sheets with an adhesive layer are applied to platinum sets. In some non-stick embodiments, a blade is held against the platinum assembly through a vacuum. In other embodiments, the blade is securely held against the platinum assembly either by an adhesive layer or by applying a vacuum.
“The cover 350 can also be in the form of a cover. A cover may be applied via a roller, a sprinkler, a brush or any other suitable applicator depending on whether the cover comprises a curable material, a thermoplastic material, a thermostable material, combinations thereof or the like. In some embodiments, a liquid is applied to a surface (eg, a surface of a platinum assembly) and subsequently cured. A top surface of the cover can define an application region. If the platinum assembly includes gap forming elements, the cover may be formed over the gap forming elements. Referring again to Figure 16, the slide retainer 330 in the form of a grip device includes a spring clip 500 that holds the slide 340. The spring clip 500 is movable between a receiving or open position. to receive slide 340 and . . the handle position to hold the slide 340. When the slide 340 is inserted between the arms 502, 504 of the handle 500, the arms 502, 504 can securely hold the edges 472, 474. After processing, the piece slide 340 can be pulled out of handle 500 without damaging slider 340 and/or without disturbing slide if slide 340 has been covered by slide. Additionally or alternatively, the slide retainer 330 may have one or more clips,
- 52 slots or other components or attributes to selectively retain slider 340. Actuator 320 of Figures 16 and 17 includes elongate members 510, 512 rotatably coupled to roller unit 310 and slider retention device 330. elongated limbs 510, | 512 can be links or other types of connectors. To move slider 340 along cover 350, an accumulator arm 580 is rotated to push up on slider retainer 330 causing elongate members 510, 512 to pivot about an axis of rotation 520 to maintain slide 340 substantially tangent to cover 350.
Processing station 300 may also include a dispenser assembly 540 for dispensing process fluids. Dispenser assembly 540 includes a pair of units 544, 546, each capable of dispensing a fluid. The outlet ports 554, 556 of the units 544, 546, respectively, may face a gap between an end 558 of the slide 340 and the cover 350. The illustrated outlet ports 554, 556 are in the form of conduits through which substances can flow. Units 544, 546 may include, without limitation, one or more fluid sources, pumps, filters or combinations thereof, as well as other fluidic components. In some embodiments, units 544, 546 -.- receive fluids from remote fluid sources and can dispense such fluids. In other embodiments, units 544, 546 may contain sources of fluid, such as fluid reservoirs. Fluid sources can be conveniently refilled or replaced when empty.
Units 544, 546 can control fluid temperature. The illustrated unit 546 of Figure 16 includes a thermal element 547 (illustrated in the imaginary line) capable of heating or cooling a fluid. the heat element
- 53 547 may include one or more heating devices (eg resistive heaters) and/or cooling devices (eg Peltier devices). Additionally or alternatively, units 544, 546 may include one or more mixing devices capable of mixing reagents.
In some protocols, two or more reagents are independently delivered to unit 544. Unit 544 may mix the two or more reagents prior to dispersion.
In other protocols, premixed reagents are delivered to units 544, 546. i | " ": Dispenser assembly 540 may also be in the form of one or more fluid dispersers, pipettes capable of loading reagents (e.g., premixed reagents, water, buffer, etc.) or the like.
If the dispenser assembly 540 includes pipettes, the pipettes can be moved to sequentially deliver substances.
A volume of a fluid (e.g., 75 microliters of a substance, 100 microliters of a substance, 500 microliters of a substance) is pipetted into the cap 350. The slider 340 is rolled to handle the liquid.
Thermal elements 680a, 680b may be activated to heat slider 340. One or more times during processing, a volume of reagent, reagent buffer, water or other substance is dispensed to, for example, restore volume, adjust concentration or similar.
Figures 27 to 29 show a method of processing a ..-c— specimen.
Generally, slider 340 is loaded into processing station 300. A substance is delivered between slider 340 and cap 350. Slider 340 is moved along cap 350 to apply substance to the specimen.
After processing, cap 350 is conveniently removed from base 360 and replaced with another cap to continue processing the same specimen or to process another | specimen.
. To load processing station 300, an end 555 (e.g., an identification end) of slide 340 may be slid into slide retainer 330. In some embodiments, end 555 is manually inserted into the device. | 5 slide retainer 330. In other embodiments, a robotic handle loads slider 340. Slider retainer 330 aligns slider 340 with processing station
300. Once loaded, slider 340 may rest on an end portion 563 of cover 350. End 558 of slider 340 extends upwardly away from cover 350 to define an opening 544. Referring to Figure 27, fluid dispenser 540 can deliver fluid 560 to opening 544. Fluid 560 can travel along a variable height range 570. Sufficient volume of fluid 560 can be dispensed to contact the specimen without moving the part. slide 340. Alternatively, slide 340 can be moved to bring fluid 560 into contact with the specimen. Figures 17 and 28 show fluid 560 (illustrated on dotted line 1 in Figure 17) applied to specimen 260. 560 reaches the gap forming elements 450, 452, the fluid 560 can accumulate the gap forming elements 450, 452, thereby keeping the fluid 560 under the slider 340. SA After the gap 570 of Figure 27 is filled with a desired volume of fluid 560, actuator arm 580 is rotated (indicated by arrow 581) about pin 582. As one end 584 of actuator arm 580 moves upward (indicated by arrow 590), actuator 320 and the slide retainer 330 cooperate to move the slider 340 along the cover 350. The slider retainer 330 can rotate freely about the axis of rotation 530 to hold the part
. 55 slide 340 next to or in contact with cover 350. Slider 340 may float in fluid 560. Cover 350 may be held securely against base 360 using vacuum and extracted through port 559 and a vacuum line
557. This ensures that the cover 350 remains stationary as the slide 340 is manipulated. In some dynamic modes of operation, the slide 340 is repeatedly moved back and forth to agitate (e.g., mix) the fluid 560. Most of the fluid 560 is rolled back and forth while the residual can be left behind. on the surface of the tissue sample. The slider 340 can move part of the fluid 560 and mix it with the layer that is left on the surface of the sample. As such, fluid 560 is continuously and vigorously mixed. The surface chemistry of the lid 350 and/or slide 340 in contact with the biological sample can be selected based on hydrophobic/hydrophilic properties that affect the amount of liquid left on the surfaces of the lid 350 and/or slide 340, A cap 350 can be hydrophilic, hydrophobic, or both. In hydrophilic embodiments, cap 350 may be made primarily of hydrophilic material to allow convenient propagation of the applied fluid. In hydrophobic embodiments, the hydrophobic cap 350 and a hydrophobic slider may be used to limit the spread of the applied fluid. In other embodiments, cap 350 can include one or more hydrophilic regions and one or more hydrophobic regions. For example, cap 350 may include a | hydrophilic central region and an outer hydrophobic region that surrounds the central region. This allows a fluid to easily propagate along the central region while the surrounding outer region provides | enhanced fluid. Cover 350's optimal surface characteristics can | be selected based on desired spread, liquid containment, and/or the properties of slide 340. When using an aqueous solution, a hydrophobic slide surface and less hydrophobic cap 350 can cooperate to keep the solution within the demarcated space by the slider 340 and the lid 350. The aqueous solution will be repelled by the hydrophobic slider 340 and propagated along the lid 350. Conversely, a hydrophilic slider 340 will propagate the solution further over the surface of the slider 562, resulting in more "puddles" on slider 340. Optimal surface characteristics of lid 350 and/or slider 340 can be selected based on liquid containment/spread. For cap mixing, a first reagent can be dispensed into cap 350. Slider 340 is rolled to collect the reagent. Slider 340 can be moved into a position on a roller to provide access between cover 350 and slider 340 while maintaining fluid pick-up. A second reagent is dispensed into the cap
350. Slider 340 is rolled to mix the reagents in consecutive roller cycles. To remove fluid 560, a waste collection member 600 from a holding position shown in Figure 27 to a waste removal position shown in Figure 29. As the waste collection member 600 reaches the waste removal position, an inlet 609 of a passage 610 of the collector member 600 is mated with an outlet 618. The refuse collector member 600 moves the actuator arm 580, which in turn moves the slide 340 to a refuse removal position, as "shown". in Figure 29. End 558 of slider 340 of Figures 29 and 30 overlaps refuse port 374 such that fluid 560 can be removed through refuse port 374, Gravity, a vacuum, materials | absorption or the like can be used to extract fluid into and through the |
-. 57: refuse port 374. In some embodiments, fluid 560 may flow through refuse port 374 into a reservoir, absorbent member, or the like.
The reservoir may be a refuse container, deposit system or the like.
The absorbent member may be made, at least in part, of a highly absorbent material, including sponge material, absorbent material, or the like.
If fluid 560 passes through refuse port 374 primarily due to gravity, an absorbent member (e.g., an O-pad or a blade) may be positioned below refuse port 374. In some embodiments, the absorbent member is directly adhered to. to the undersurface of cap 350. Of course, the absorbent member can be in any other suitable location, if necessary or desired.
If a vacuum is applied through passage 610, fluid 560 can flow along capillary gap 570 towards and ultimately through waste port 374. Figure 30 shows fluid F flowing downwards through | from the refuse port 374 and through the inlet 380 of the base 360. Fluid F proceeds along a passage 620 towards the outlet 618. In this manner, fluid F flows along a fluid path through the cap 350 and the base 360. In some embodiments, substantially no residual liquid 560 remains in the gap 570 after the vacuum has been applied for a sufficient length of time.
Appropriate surface finishes (e.g., surface smoothness) and surface energy (e.g., the energy determined by the surface chemistry of the cap 350) can be selected to enhance the tendency of fluid 560 to flow smoothly and completely from the 570 range. A higher level of smoothness and lower surface energy will favor migration over the 570 range, while more surface imperfections and higher surface energy 58 will tend to retain the 560 liquid in the 570 range.
A flow inhibitor 390 of Figure 30 may minimize, limit, or substantially prevent the flow of fluid away from inlet 380 along the interface of cap 350 and base 360. Flow inhibitor 390 may be an annular U-shaped channel that surrounds inlet 380. If fluid migrates along an interface 640, fluid will flow into and collect in the inhibitor. .- flow 390. The flow inhibitor 390 can thus serve as a reservoir and can be periodically emptied. Any amount of =] flow inhibitors, sealing members, relief features or the like may be used to minimize, limit or substantially prevent the flow of fluid under the cap 350 due to absorbing and/or capillary action.
In some embodiments, including the illustrated embodiment of Figure 27, the base 360 includes thermal elements 680a, 680b (collectively "680") adapted to convert electrical energy to thermal energy. 680 Thermal Elements can support different protocols that require | thermal cycling, equally fast thermal cycling for ISH, IHC or similar. When the thermal elements 680 generate heat, the heat is transferred through the cap 350 to the specimen. The amount of electrical energy delivered to the 680 thermal elements can be increased or decreased to increase or decrease the temperature of the specimens and processing liquid.
| Thermal elements 680 may be resistive heating elements. Different types of resistive heating elements (eg plate resistive heaters, coil resistive heaters, strip heaters or the like) can be selected based on desired operating parameters. Other types of thermal elements such as cooling elements, heating/cooling elements or the like may be used. As used in the present invention, the term
- 59 “cooling element” is a broad term that includes, without limitation, one or more elements capable of actively absorbing heat so as to effectively cool at least a portion of the sample, processing fluid, and/or slide 340. For example, a cooling element may be a —cooling tube through which a cooled fluid flows.
In some embodiments, the elements 680 are ANNA heating/cooling elements, such as Peltier devices. Peltier devices can be solid state components that become hot in NS | one side and cold on the opposite side, depending on the direction of current passed through them. By simply selecting the current direction, the Peltier device can be used to heat the slide 340 for a desired length of time. By switching the direction of current, elements 680 cool slider 340. In other embodiments, cooling/heating elements 680 are channels through which a working fluid flows. Heated fluid may be passed through the channels for a heating period and a cooled fluid may be passed through the channels for a cooling period. The position, number and type of cooling/heating elements 680 can be selected based on the desired temperature profile of the base 360.
Additionally or alternatively, cover 350 may include thermal elements, such as heating elements to produce heat during a heating period and cooling elements to absorb heat during a cooling period. For example, the lid 350 may have one or more embedded thermal elements. When the cover 350 is mated with the base 360, the electrical connection can be established such that the base 360 supplies electrical power to the thermal elements.
Thermal devices may also be used to transfer heat through the slider 340. Such thermal devices may
'6o be placed on the rear side of the slider 340 to transfer heat through the slider 340 to the specimen.
In some embodiments, both the cap 350 and a thermal device on the backside of the slide 340 cooperate to control the temperature of the specimen.
In some modes of operation, the thermal device overlaying the slider 340 may transfer heat through the slider 340 to a specimen.
To cool the specimen, thermal devices (eg, cooling channels) in the lid 350 can absorb heat.
In this way, the specimen can be heated or cooled.
Figure 31 shows a coloring system 700 with an arrangement of slide processing stations.
The 700 staining system is shown with sliders loaded at each of the processing stations. Some slider processing stations include fluid dispensers to automatically process specimens.
An operator or an external fluid delivery system can deliver fluids to the sliders at processing stations without fluid dispensers.
The external fluid delivery system may be a robotic pipette system.
In other embodiments, all processing stations may include fluid dispensers such that each processing station can perform an individual protocol.
Readers can be embedded in processing stations and can acquire information from the slide to determine an appropriate protocol.
Each of the processing stations can be mechanically connected to a drive mechanism 702. The drive mechanism 702 can be moved vertically (indicated by arrows 704, 706) to move the sliders.
By way of example, an end 720 of the arm actuator 580 of Figure 27 may be coupled to a circular plate 730 of the drive mechanism 702. The circular plate 730 is moved
61' down (indicated by arrow 706 in Figure 31) to move the sliders radially inward and is moved up (indicated by arrow 704 in Figure 31) to move the sliders radially outward. The fluid dispensers remain stationary as the sliding parts are moved. To simultaneously process the specimens, the fluid dispensers can dispense the fluid to the respective processing stations when the plate 730 is in an elevated position. After dispensing, the plate 730 can be moved up and down repeatedly to oscillate each of the microscope slides to agitate the fluids. The plate 730 can be rotated about an axis of rotation 731 to move the sliders to the stationary fluid dispensers to perform an entire protocol without removing the sliders. Applied liquids can be removed from each slide at a desired time. This allows the individualized slide to process at each station.
The drive mechanism 702 may also include, without limitation, one or more motors, gear trains, linear sliders, actuators, piston assemblies, combinations thereof or the like. The components of the drive mechanism 702 can be selected based on the arrangement of processing stations.
To provide independent parallel processing, each ---—processing station- can be connected to an independently operable drive mechanism. Different protocols can be performed on different stations.
In some embodiments, the coloring system 700 is a carrier-based colorant. Sliding parts can be loaded manually or by using a separate loader. Sliding parts can be loaded at a particular location, for
- 62 example, every 15 to 20 seconds. The circular arrangement of slide holders (including sliders, handles, clamps, disposables, curved upper parts, etc.) may be periodically advanced to an adjacent fluid dispenser. Other components of the staining station 700 may remain stationary (eg, fluid dispensers, waste ports, etc.). For hematoxylin and eosin staining (H&E staining), the sliders are moved around the wheel so that the specimens receive different liquids in the proper order and timing. Multiple liquids can be propagated to accommodate different protocols. In the last season, the sliding parts can be covered with coverslips and then removed from the wheel. Fluid dispensers can be added to or removed from the illustrated 700 staining system to perform different types of protocols. The 700 staining system thus provides processing flexibility to perform primary staining, special staining, IHC, IHS, H&E staining or similar.

Processing can be | optimized by determining, for example, an optimal schedule to increase processing speeds, to increase throughput (for example, a number of sliding parts processed in a length of time) or the like. Such an optimal schedule may be a schedule for preparing and delivering slide parts to the coloring system 1105. In some embodiments, the control system 1120 determines loading sequences to reduce processing wait times. Control system 1120 can also be programmed such that loading of pipettes, nozzles or fluid dispensers for the next specimen can begin while processing the currently loaded specimen. This saves time because fluids can be dispensed into the next specimen as soon as the current specimen is removed from the station.
