  Each or 6/Set
PAP Pen Liquid Blocker Part 6505
PAP Pen Liquid Blocker, Mini Part 6506

 

APPLICATION:

Newcomer Supply PAP Pen Liquid Blocker, hydrophobic slide markers creates a visible hydrophobic barrier that provides proper surface tension to hold reagents within a targeted area when applied around tissue sections or smears on a microscopic slide. This barrier ensures the amount of reagent needed is reduced and retained for complete tissue coverage and staining reaction. Multiple specimens can be separated by drawn circles or lines applied to the same slide. The PAP Pen, Mini provides a finer pen tip for drawing a thinner barrier film.

PAP Pen Liquid Blockers contain a unique formulation that is water repellent, insoluble in alcohol and acetone, soluble in xylene and temperature resistant up to 120°C.

 

METHOD:

Technique:  Paraffin, frozen sections and smears

      • Manual immunohistochemistry (IHC) procedures
      • Manual immunofluorescence (IF) procedures
      • Manual In-Situ hybridization (ISH) procedures
      • Manual enzyme procedures

 

PAP PEN ACTIVATION INSTRUCTIONS:

    1. Vigorously shake capped pen for approximately 10 seconds.
    2. Remove cap; hold pen upright and depress tip 2-3 times.
    3. Invert pen, press tip lightly on absorbent paper until tip is visually saturated. Release pressure on tip and blot away any excess liquid.
    4. Practice applying a thin PAP Pen liquid barrier on a test slide using minimal pressure. Too much pressure may result in excess barrier solution creating a wider film that could touch tissue edges.
    5. Store PAP Pen Liquid Blocker at room temperature, tightly capped on a horizontal flat surface.
    6. Pen re-activation not required unless tip dries out during storage.

 

PROCEDURE:

    1. Paraffin Section Method:
        1. Deparaffinize sections thoroughly in xylene and hydrate through 100% and 95% ethyl alcohols. Wash well with distilled water.
        2. Remove slide from water, blot excess solution from slide and tissue section. Or place long edge of slide on absorbent material to remove excess moisture.
        3. Encircle tissue section on slide surface with PAP Pen as illustrated. Do not touch the pen to any edges of the tissue.
        4. The liquid barrier can be drawn on a slightly damp slide.
        5. See Procedure Notes #1 and #2.
    2. Frozen Section and Smear Method:
        1. Encircle frozen tissue section or smear on slide at room temperature with the PAP Pen. Do not touch the pen to any edges of the tissue section or smear.
        2. The PAP Pen barrier should be applied before fixation or prior to immersion of slide into water or buffer.
        3. See Procedure Notes #1 and #2.
    3. After liquid barrier application, allow barrier film to dry before proceeding with staining procedure.
        1. See Procedure Note #3.
    1. Drain/rinse reagents off between staining steps; blotting slide and tissue as needed to remove excess solution.
        1. See Procedure Note #4.
    2. Complete staining; coverslip with compatible mounting medium.

 

PROCEDURE NOTES:

    1. Once a tissue section is touched with PAP Pen liquid barrier it cannot be removed. The section remains usable but colorization will result on the touched portion of tissue.
    2. If the tissue section is not completely encircled by the PAP Pen Liquid Blocker barrier film, reagents will not be fully retained on the section and flood out onto the slide. This may compromise adequate tissue coverage by reagents.
    3. If liquid barrier lines are not completely dry prior to staining, a precipitate from reaction with reagents may occur.
    4. The use of Slide Moisture Chamber (68431, 68432) or StainTray™ (6847, 6848) is recommended for manual staining to maintain slide organization and a moist environment during the procedure.

    19. Quickly dehydrate in two changes each of 95% and 100% ethyl alcohol. Clear in three changes of xylene, 10 dips each; coverslip with compatible mounting medium.

 

RESULTS:

Reticular fibers Black
Background Red

 

PROCEDURE NOTES:

    1. Acid clean all glassware/plasticware (Part 12086) and rinse thoroughly in several changes of distilled water.
    2. No metals of any kind should come in contact with silver solutions to prevent precipitation of silver salts.  Use plastic forceps (Part 5500) or paraffin coated metal forceps.
    3. Drain slides after each step to prevent solution carry over.
    4. Do not allow sections to dry out at any point during procedure.
    5. This rinse step is critical for good reticulum demonstration. If rinsing is insufficient, excessive background staining may occur.
    6. If black reticular fibers are not evident or are lightly/poorly stained, return all slides to Ammoniacal Silver Working Solution (Step #11) and repeat Steps 11-14 with the same timings.
    7. Wash well after Nuclear Fast Red Stain, Kernechtrot to avoid cloudiness in dehydration steps.
    8. If using a xylene substitute, follow manufacturer’s recommendation for deparaffinization and clearing steps.

The MAS-GP adhesive microscope slide surface has an enhanced chemistry coating that is bound on the glass surface and creates a very strong adhesive and hydrophilic surface for tissue sections and cells to adhere to.

The MAS-GP adhesive microscope slide can be widely used for pathology, cytology and immunohistochemistry applications.

The hydrophilic surface of the microscope slide ensures faster draining of the water between the glass surface and the tissue section compared to adhesive slides with a hydrophobic surface.  This can help minimize any water being trapped between the tissue section and the microscope slide when the tissue section is being picked up from the water bath.  Minimizing the trapped water can increase the area of the tissue section being in direct contact with the adhesive coating on the microscope glass and maximizing the adhesive bond between the tissue section and microscope glass.  Thus, creating stronger adhesive properties of the MAS-GP microscope slide.

 

ADHESIVE MECHANISM OF THE MAS-GP ADEHESIVE MICROSCOPE SLIDE:

A coating is applied to the microscope slide surface by a covalent bond of the enhanced aminosilane and OH groups to produce a strong positive charge on the slide.  Tissue sections, having a negative charge, will be attracted to the surface of the glass and adhere to it.  The MAS-GP adhesive microscope slide has a high tissue section & cell adhesive strength.  The microscope slide is highly durable to thermal treatment particularly with microwave and autoclave.

 

RECOMMENDED USE:

  • Manual & automated IHC applications

The TOMO adhesive microscope slides are an incredible slide to work with on automated IHC stainers!  The advanced technology in manufacturing the adhesive surface of the microscope slide produces outstanding adhesion to the tissue section even in the most demanding applications.  The surface of the TOMO adhesive microscope slide is hydrophilic producing two very notable features:

  • Allows to refloat the tissue in the water bath for repositioning the tissue section
  • Allows the microscope slide to be used on all automated IHC platforms

 

The hydrophilic surface of the microscope slide also ensures faster draining of the water between the glass surface and the tissue section compared to adhesive slides with a hydrophobic surface.  This can help minimize any water being trapped between the tissue section and the microscope slide when the tissue section is being picked up from the water bath.  Minimizing the trapped water can increase the area of the tissue section being in direct contact with the adhesive coating on the microscope glass and maximizing the adhesive bond between the tissue section and microscope glass.  Thus, creating stronger adhesive properties of the TOMO Adhesive microscope slide.

Designed specifically for biopsy processing by using <1mm square openings in the lid and base surfaces for max fluid flow & specimen retention. Covers detached and packaged separately.

We got the PAs involved again in designing this beauty! We took the basic design of the 15cm ruler and stretched it out to 30cm. All metric and the numbers on the top and bottom both start on the left to accommodate both the top and bottom readers. For those of you that flip the ruler for the large tissue section measurements, it’s not only flush cut at zero, but also at 30cm. Not to be out done by the 15cm ruler, this one is also printed on both sides!

PROCEDURE:

    1. Fix bone for a length of time sufficient for specimen size and type.
        1. See Procedure Note #2.
    2. Adequate bone fixation is essential before decal solution exposure.
    3. Wash fixed specimen in running tap water for 10 minutes.
    4. Submerge fixed bone segment in Decalcifying Solution, HCL/EDTA, covering specimen at a 20:1 ratio.
        1. See Procedure Notes #3 and #4.
    5. Check specimen regularly for sufficient solution coverage. Change solution daily and do not add or mix fresh solution with old.
    6. Decalcification time will vary, dependent on bone size and weight.
        1. Check light bone samples every 30 to 60 minutes.
        2. Check compact bone samples every 1 to 2 hours.
        3. Bone marrow or light bone biopsies, on average, will decalcify in 1 to 2 hours.
        4. 3 mm thick section of femoral head, on average, will decalcify in 3 to 4 hours.
    7. Check decal completion at regular intervals with Decalcification End Point Set (Part 1051) to deter over-decalcification.
        1. See Procedure Note #5.
    8. Wash in running tap water when decalcification is complete.
        1. Wash small samples 30-60 minutes.
        2. Wash larger bones 1-4 hours.
        3. Additional trimming of decaled bone can occur at this point to size and thickness suitable for tissue processing.
    9. Proceed with tissue processing procedure for bone specimens.
    10. Trim block and section bone. If trimming or sectioning is impaired due to bone hardness, surface decalcification is recommended.
        1. See Procedure Note #6.
    11. Perform surface decalcification: Soak exposed tissue surface side down in recommended decalcifying solution for 15-60 minutes. Rinse block with distilled water to remove corrosive acids and re-section.

    2. Reduce size of a large bone by bisecting bone into smaller pieces, removing excess soft tissue for faster fixation. Maximum bone thickness of 3-5 mm is recommended.
    3. Decal solution should be in contact with all specimen surfaces. For multiple pieces, ensure pieces are separated or suspended and not in direct contact or stacked on each other.
    4. Enhance decal with low-speed agitation shaker, rotator or stir plate.
    5. Decalcification end-point testing can also be done with specimen radiography. Physical probing of bone is not recommended.
    6. Decalcifying Solution, HCL/EDTA is not a preferred product for surface decalcification. Decalcifying Solution, Formic Acid 5%, Aqueous (Part 1049) and Decalcifying Solution, Formic/Citrate (Part 10492) are recommended for surface decalcification.
    7. Only a few calcium-free sections will be obtained after surface decalcification. Repeat the process for additional sections.

For storage requirements and expiration date refer to individual bottle labels.

 

APPLICATION:

Newcomer Supply Buffer Solutions for Epitope Retrieval procedure provides a choice of two ready-to-use buffers for antigen retrieval. The majority of epitopes/antigens are masked in formalin fixed paraffin embedded (FFPE) tissues.  Antigen retrieval methods improve antibody binding by de-masking the FFPE chemical modification of epitopes through heat induced epitope retrieval (HIER) procedures when performed prior to immunohistochemical (IHC) staining.

No retrieval buffer is optimal for all tissue antigens. The choice of buffer will depend upon the suggested retrieval buffer specific to an individual antibody.  Refer to each antibody datasheet for recommended chemical composition and pH value of retrieval buffer.

    • Part 1056: EDTA Buffer 0.001M, pH 8.0 is an alkaline buffer optimal for use with primary antibodies that require an EDTA buffer at a higher pH for HIER.
    • Part 10355: Citrate Buffer 0.01M, pH 6.0 is an acidic buffer optimal for use with primary antibodies that require a citrate buffer at a lower pH for HIER.

 

METHOD:

Fixation: Formalin 10%, Phosphate Buffered (Part 1090)
Technique: Paraffin sections on adhesive slides
Solutions: All solutions are manufactured by Newcomer Supply, Inc.

 

EPITOPE RETRIEVAL PROCEDURE:

    1. Choose a HIER procedure that suits the laboratory and anticipated workload.
        1. Instrumentation and methods for HIER include but are not limited to; microwave, pressure cooker and steamer methods.
    2. Validate instrumentation according to manufacturer’s suggested instructions for antigen retrieval methods.
    3. After validation of instrumentation and methodology; deparaffinize sections thoroughly in three changes of xylene, 3 minutes each. Hydrate through two changes each of 100% and 95% ethyl alcohols, 10 dips each.  Wash well with distilled water.
        1. See Procedure Notes #2 and #3.
    4. Proceed with a validated method of HIER per established protocol implementing either EDTA Buffer 0.001M, pH 8.0 (Part 1056) or Citrate Buffer 0.01M, pH 6.0 (Part 10355).
    5. After completion of HIER, allow sufficient time for slides to cool before proceeding with IHC protocol.

 

PROCEDURE NOTES:

    1. Drain slides after each step to prevent solution carry over.
    2. Do not allow sections to dry out during procedure.
    3. If using a xylene substitute, follow manufacturer’s recommendation for deparaffinization and clearing steps.
