IPC Blue™ Tissue Marking Dyes are a proprietary formula made with Toluidine Blue biopsy marking dye in a 10% neutral buffered formalin.

  • Economical – one drop per biopsy.
  • Convenient dispenser bottles prevent product from spilling or drying out.
  • Continues fixation while grossing.
  • Can be added directly to your tissue or on the tissue processor.

 

BENEFITS OF THE IPC BLUE™ TISSUE MARKING DYES:

  • Dark blue color allows better visualization of biopsy during embedding & cutting.
  • Do not interfere with any other staining.  The IPC Blue™ Dye is totally replaced when the slide is stained.  (When Eosin is used as the marking dye, the tissue section will remain stained with Eosin).
  • IPC Blue™ Tissue Marking Dyes do not evaporate as quickly as Eosin, because it is formalin based instead of alcohol based.

 

IPC BLUE™ TISSUE MARKING DYES DIRECTIONS FOR USE:

At the Grossing Station: One to two drops are placed on a biopsy.

On the processor:  1 oz. of IPC Blue™ Tissue Marking Dye is added to the first formalin.  (It is important to note that Eosin CANNOT be used on the tissue processor, as this will remove and replace IPC Blue™ Tissue Marking Dye in the specimen).

The recommended application is to add 1 oz. to the first formalin and then rotate it to the second formalin before changing.

PRACTICAL APPLICATION OF FORMIC ACID 96%, ACS:

Formic Acid 96%, ACS can be used in histology/autopsy as a additional step after fixation to reduce CJD infectivity.

 

TECHNICAL NOTES FOR USING FORMIC ACID 96%, ACS:

Do not reuse open bottle.  Use fresh bottle each time

 

KEY COMPONENT:

>95% FORMIC ACID

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

 

APPLICATION:

Newcomer Supply Lymph Node Grossing Aid is a ready-to-use fixative that serves as either a primary or secondary fixative to enhance the visibility and yield of lymph nodes in specimens in which lymph node examination is critical, such as; breast, colon, lung, radical neck dissection, small intestine and omentum.

The combination of formaldehyde, ethanol and acetic acid in the Lymph Node Grossing Aid solution allows for rapid tissue penetration.  Following sufficient fixation/immersion lymph nodes will be visibly grayish in color, noticeably standing out from surrounding tissues and readily identifiable.

 

METHOD:

Fixation:

Larger Biopsies: A minimum of 10-12 hours is recommended.

Small Biopsies:  A minimum of 4 to 6 hours is recommended.

Solutions:  All solutions are manufactured by Newcomer Supply, Inc.

 

FIXATION PROCEDURE:

    1. Place fresh tissue in an adequate amount of Lymph Node Grossing Aid solution as soon as possible after surgical excision.
        1. See Procedure Note #1.
    2. Gross tissue specimen in a manner to allow Lymph Node Grossing Aid to adequately penetrate.
        1. Breast tissue: work with entire specimen or remove a smaller area with suspected lymph nodes. Bread loaf tissue to increase surface area and promote efficient fixative penetration.
        2. Colon tissue: cut open, rinse and pin-out, work with either a segment(s) of colon or entire specimen.
        3. Other specimens: gross to increase tissue surface area and promote efficient fixative penetration.
    3. Return specimens to Lymph Node Grossing Aid solution and fix for a sufficient amount of time, depending upon size and type of tissue.
    4. After adequate immersion in Lymph Node Grossing Aid, remove specimen and re-gross.
        1. Remove adipose and palpate for lymph nodes and/or identify nodes by their visibly grayish color.
    5. Hold tissues in either Lymph Node Grossing Aid or Formalin 10%, Phosphate Buffered (Part 1090) until ready to process.
        1. See Procedure Note #2.

 

PROCEDURE NOTES:

    1. A specimen initially received in Formalin 10%, Phosphate Buffered can remain in fixative until initial grossing occurs, then transferred to Lymph Node Grossing Aid solution as a secondary fixative.
    2. Extended storage in Lymph Node Grossing Aid is not recommended. After fixation, transfer Lymph Node Grossing Aid wet tissue to Formalin 10%, Phosphate Buffered for long-term storage.

Tissue Microarray (TMA) is a technique enabling tissues from many donor blocks to be arrayed on a single slide.  The array mold is specifically designed to be simple, easy to use and inexpensive.  Tissues can be analyzed in the same conditions enhancing the efficiency of the research.

The mold kit will allow you to perform TMAs faster while giving excellent results.  By using array molds, you can process up to 170 specimens onto one single slide in very little time.

BENEFITS OF THE TISSUE MICROARRAY MOLDS:

  • Mold made of silicone
  • 45° cut corner on one corner for sample orientation
  • View many different samples on the same slide
  • Process up to 170 specimens onto one slide
  • Easily stored in a drawer
  • Can be reused hundreds of times without losing its flexibility
  • Withstands temperatures from -100°C to +250°C

INSTRUCTIONS FOR USE:                                      

1 Place the mold in an oven for 30 minutes at 70°C to 80°C.
2 Slowly dispense liquid paraffin (60°C to 65°C) until the top of core rods are fully submerged.  If bubbles are formed, remove them with a pair of heated forceps.
3 Position a cassette on the mold.
4 Fill embedding cassette with paraffin.
5 Cool at room temperature or at about 4°C for 30 to 60 minutes.  Warning:  At lower temperatures, cracks may appear in the block.
6 Slowly separate the mold from the embedding cassette.
7 Trim paraffin around the edges of the recipient block.
8 Extract the marked tissue from the donor block by using the appropriate tissue punch.

a.  Place the donor block on a horizontal and flat surface.

b.  Hold the tissue punch in your hand perpendicularly to the marked position of the donor block.

c.  Slowly insert the tissue punch into the donor block at the proper depth of 5mm.  Don’t insert it too quickly and too deep to prevent damaging the donor block and the tissue punch.

9 By slowly pushing on the tissue punch plunger, deliver the extracted tissue into the corresponding hole of the recipient block.  Then, gently push in all the tissue cores to ensure evenness for microtomy.
10 Place the recipient block on a glass slide (facing down) and incubate the block at 37°C to 45°C for 3 hours up to overnight.  The delivered cores will adhere to their respective holes in the recipient block.  Do not pull the slide from the TMA block.
11 With the recipient block still warm and tacky, heat another slide in an oven to around 70°C for approximately 10 minutes.  Then, place it under the slide that is already stuck to the Array block.  The Array block surface should quickly turn to liquid.  Move the two slides around on the Array block to push any surface air bubbles away and to flatten the Array block surface.
12 Now, remove second slide and place Array block with original slide (slide down) on counter for 10 minutes in order to cool down.  Once Array block is at room temperature, place it with the slide on an ice tray (no water) to cool for 20 minutes.  Slide should remove easily from Array block which will now be ready for cutting.

 

Notes:

  1. The tissue punches are not intended for use directly on patients.  For lab/research purposes only.
  2. If some of the mold cores are not needed, simply fill unwanted holes in the paraffin Array block with blank paraffin cores.
  3. If the Array mold has cracked or split, you can still use it by placing a rubber band or tape around it.  This will keep the Array mold together when paraffin is poured into it.

APPLICATION:

Newcomer Supply Eosin-Phloxine Stain Set solutions are aqueous based, provide a finer touch to hematoxylin and eosin stains and can be used in either manual or automated staining platforms.  Differentiation of muscle, connective tissue and epithelial elements tend to be sharper and better demonstrated than with the traditional eosin y solution alone.

Hematoxylin and eosin (H&E)  staining is used for screening specimens in anatomic pathology, for research, smears, touch preps and other applications.  Its two primary coloring agents stain all cellular material: nuclei (blue), and cytoplasmic elements (pink-red).  Popularity of this stain is due to its simplicity, ability to clearly demonstrate a variety of tissue components, dependability, repeatability, and speed of use.

Quality Control: Since hematoxylin and eosin staining is the foundation of the diagnostic process, maintaining quality is of critical importance. Procedures will vary between laboratories depending upon volume of slides, automation vs manual staining, chemical hygiene and solution integrity.  The longevity of eosin depends upon these factors and stain quality should be regularly screened with an H&E control slide.

APPLICATION:

Newcomer Supply Eosin Y Stock Stain 1%, Aqueous provides the key component of an Eosin Y Working Solution in the hematoxylin and eosin stain and can be used in either manual or automated staining platforms.  Eosin’s value is in its ability to distinguish between the cytoplasm of different types of cells by staining cytoplasmic components differing shades and intensities of pink to red.

Hematoxylin and eosin (H&E) staining is used for screening specimens in anatomic pathology, for research, smears, touch preps and other applications.  Its two primary coloring agents stain all cellular material: nuclei (blue), and cytoplasmic elements (pink-red).  Popularity of this stain is due to its simplicity, ability to clearly demonstrate a variety of tissue components, dependability, repeatability, and speed of use.

APPLICATION:

Newcomer Supply Eosin Y Working Solution is a ready to use counterstain in the hematoxylin and eosin stain and can be used in either manual or automated staining platforms.  Eosin’s value is in its ability to distinguish between the cytoplasm of different types of cells by staining cytoplasmic components differing shades and intensities of pink to red.

Hematoxylin and eosin (H&E) staining is used for screening specimens in anatomic pathology, for research, smears, touch preps and other applications.  Its two primary coloring agents stain all cellular material: nuclei (blue), and cytoplasmic elements (pink-red).  Popularity of this stain is due to its simplicity, ability to clearly demonstrate a variety of  tissue components, dependability, repeatability, and speed of use.

Quality Control: Since hematoxylin and eosin staining is the foundation of the diagnostic process, maintaining quality is of critical importance. Procedures will vary between laboratories depending upon volume of slides, automation vs manual staining, chemical hygiene and solution integrity.  The longevity of eosin depends upon these factors and stain quality should be regularly screened with an H&E control slide.

 

METHOD:

Fixation:  Formalin 10%, Phosphate Buffered (Part 1090)
Technique:  Paraffin sections cut at 4 microns
Solutions:  All solutions are manufactured by Newcomer Supply, Inc.

APPLICATION:

Newcomer Supply Eosin Y Stock Stain 1%, Alcoholic provides the key component of an alcohol-based Eosin Y Working Solution in the  hematoxylin and eosin stain and can be used in either manual or automated staining platforms.  Eosin’s value is its ability to distinguish between the cytoplasm of different types of cells by staining cytoplasmic components differing shades and intensities of pink to red.

Hematoxylin and eosin (H&E) staining is used for screening specimens in anatomic pathology, for research, smears, touch preps and other applications.  Its two primary coloring agents stain all cellular material: nuclei (blue), and cytoplasmic elements (pink-red).  Popularity of this stain is due to its simplicity, ability to clearly demonstrate a variety of tissue components, dependability, repeatability, and speed of use.

Quality Control: Since hematoxylin and eosin staining is the foundation of the diagnostic process, maintaining quality is of critical importance. Procedures will vary between laboratories depending upon volume of slides, automation vs manual staining, chemical hygiene and solution integrity.  The longevity of eosin depends upon these factors and stain quality should be regularly screened with an H&E control slide.

 

METHOD:

APPLICATION:

Newcomer Supply Decalcification End Point Set uses a chemical testing method for detecting the presence of released calcium and determining the completion point of bone decalcification process.  This procedure will avoid over decalcification and limit the decalcifying process to what is needed to maintain a high-quality specimen.  Decalcification End Point Set can be used with either acid or chelating decalcifying agents.

 

METHOD:

Fixation:  Fully fixed bone specimen in fixative of choice.
Solutions:  All solutions are manufactured by Newcomer Supply, Inc.

 

PROCEDURE:

    1. Submerge fixed and washed bone segment in decalcifying solution of choice, adequately covering specimen at a 20:1 ratio.
    2. Check specimen regularly for adequate solution coverage. Change solution daily and do not add or mix fresh solution with old.
    3. Decalcification time will vary, dependent on specimen type, thickness and strength of the decalcifying agent used.
    4. Check completion of decal with Decalcification End Point Set. Prepare a test aliquot by pipetting and combining in a 20 ml beaker:
        1. Solution A: Ammonium Hydroxide, Aqueous      5 ml
        2. Solution B: Ammonium Oxalate, Aqueous       5 ml
        3. Used decal solution from specimen container   5 ml
        4. Avoid pipetting up particulates from used solution
    5. Mix well; allow test aliquot to stand for 15 minutes.
    6. Decalcification is complete if test aliquot is clear.
        1. Clear indicates solution is calcium free and decalcification has reached an end point stage.
        2. Proceed to Step #8.
    7. Decalcification is incomplete if the test aliquot is cloudy.
        1. Cloudy indicates presence of calcium oxalate and decalcification is incomplete.
        2. Transfer specimen into fresh decalcification fluid and continue to repeat Step #3 – Step #6 until decalcification end point stage is reached.
    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.

       

PROCEDURE NOTE:

    1. Decalcification end-point testing can also be done with specimen radiography. Physical probing of bone is not recommended.

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

 

APPLICATION:  

Newcomer Supply Decalcifying Solution, Formic Acid, 5% Aqueous, provides a moderate rate of decalcification while maintaining excellent cellular morphology.  This solution is a general purpose decalcifier and is suitable for all bone specimen types from sternal or iliac crest bone marrow biopsies (light bone) to femoral head and long bone sections (compact bone).

 

METHOD: 

Fixation:  Formalin 10% Phosphate Buffered (Part 1090)

  1. See Procedure Note #1.

Technique:  Paraffin sections cut at 5 microns on adhesive slides
Solutions: All solutions are manufactured by Newcomer Supply, Inc.

 

PROCEDURE: 

  1. Fix bone specimen in fixative of choice, for a length of time sufficient for specimen size and type.
  1. See Procedure Notes #2 and #3.
  1. Wash fixed specimen in running tap water for 10 minutes.
  2. Submerge fixed bone segment(s) in container of Decalcifying Solution, Formic Acid 5%, Aqueous that adequately covers the specimen. A 20:1 ratio is recommended.
  1. See Procedure Notes #4 and #5.
  1. Check the specimen regularly for adequate solution coverage during the decalcification process for optimal decalcifying reaction.  Decalcification time will vary and is dependent on size and weight of bone.
    1. Check light bone samples every 30 to 60 minutes; check compact bone samples every 1 to 2 hours.
    2. Bone marrow or light bone biopsies, on the average, will decalcify in 4 to 6 hours.
    3. A 3 mm thick section of femoral head, on the average, will decalcify in 8 to 24 hours.
  2. Check completion of decalcification with Decalcification End Point Set (Part 1051) regularly to deter over-decalcification and loss of cellular morphology.
  1. See Procedure Note #6.
  1. Wash the specimen in running tap water when decalcification is judged to be complete.  Suggested time for small samples is 30-60 minutes; larger bones 1-4 hours or according to laboratory protocol established times.
  1. Additional trimming of decalcified bone can occur at this stage to a size and thickness suitable for tissue processing.
  1. Proceed with laboratory tissue processing procedure for bone specimens.
  2. Trim block(s) and section the processed, paraffin embedded bone; if block trimming or sectioning is impaired due to bone hardness, surface decalcification is recommended.
  3. Perform surface decalcification by soaking the paraffin block with exposed tissue surface side down in Decalcifying Solution, Formic Acid 5%, Aqueous for 15-60 minutes. Rinse block thoroughly with distilled water to remove corrosive acids and re-section.
  1. See Procedure Note #7.

 

PROCEDURE NOTES:

  1. Other fixatives that provide satisfactory results for bone specimens are:  AZF Fixative (Part 1009), B-5 Fixative Modified, Zinc Chloride (Part 1015), Bouin Fluid (Part 1020), Zamboni Fixative (Part 1459) and Zinc Formalin Fixative (Part 1482).
  2. If possible, reduce the overall size of a larger bone specimen by bisecting or cutting the bone into smaller pieces and remove any excess attached soft tissue or skin for faster fixation.  A maximum bone thickness of 3-5 mm is recommended.
  3. To ensure optimal staining results, adequate fixation of bone is essential before exposing specimen to decalcification solution.
  4. Decalcification solution should be in contact with all specimen surfaces.  If multiple pieces are in one container, ensure that pieces are separated and/or suspended and not in direct contact or stacked on top of each other.  Change the solution at least daily and never add to or mix fresh solution with old.
  5. Decalcification can be enhanced with the use of low speed agitation with either a stir bar/stir plate or rotator/shaker.
  6. Decalcification end-point testing can also be accomplished through specimen radiography. Physical testing (probing or bending) of the bone is not recommended.
  7. Surface decalcification removes only a thin layer of residual calcium from the tissue block surface.  This will allow only a few calcium-free sections to be obtained. Repeating the surface decalcification process for additional sections may be required.

Tissues placed in Davidson Fixative turn white/opaque, enhancing the visibility and yield of lymph nodes in fatty breast, colon and radical dissections.  Overnight fixation is recommended for large and/or fatty specimens and lymph node detection.

 

METHOD:

Fixation Recommendations:

    • Small Biopsies: Up to 24 hours.
    • Mice Eyes: Up to 12 hours.
    • Rat and Rabbit Eyes: Up to 24 hours.
    • Large Eyes (human or animal): 48-72 hours.
    • Mollusks: 24-48 hours.
    • Lymph Nodes: Up to 24 hours. Small nodes (5 mm or less) should be halved.  Dissect larger nodes so that no piece is thicker than 2-3 mm.

Solutions:  All solutions are manufactured by Newcomer Supply, Inc.

 

FIXATION PROCEDURE:

    1. Place tissue directly in Davidson Fixative after excision.
        1. See Procedure Note #1.
    2. Fix in Davidson Fixative for the recommended fixation time.
        1. See Procedure Note #2.
    3. Rinse Davidson fixed tissue in distilled water; 1-2 minutes.
    4. Hold tissue in either Formalin 10%, Phosphate Buffered (Part 1090) or in 70% Ethyl Alcohol (Part 10844) prior to processing.

 

PROCEDURE NOTES:

    1. If initially received in Formalin 10%, Phosphate Buffered, rinse specimen in tap water prior to placing in Davidson Fixative.
    2. Extended storage in Davidson Fixative may result in hard, brittle tissue. After recommended fixation time, transfer Davidson fixed tissue to 70% Ethyl Alcohol or Formalin 10%, Phosphate Buffered for storage.

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
    • 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.

        1. Use sufficient solution to completely cover slides.
        2. Keep solution covered to avoid evaporation.
    3. Soak slides in the Aminoalkylsilane Slide Adhesive for 2 minutes.
        1. See Procedure Notes #1 and #2.
    4. Rinse slides well in three changes of distilled water; 5 dips each.
        1. Thorough rinsing removes excess adhesive and reduces occurrence of background staining.
    5. Drain slides. Blot and tap excess water to prevent water spotting.
    6. Dry slides in a 60°C oven for a minimum of 30 minutes or overnight at room temperature.
    7. Store dried treated slides in a clean slide box at room temperature.
        1. Slides will adhere together if not thoroughly dried before storing.
    8. Wash emptied slide racks after use to ensure adhesive is removed.

 

PROCEDURE NOTES:

    1. Store used Aminoalkylsilane Slide Adhesive in a separate well sealed container; reuse for up to three weeks.
    2. 250 ml of Aminoalkylsilane Slide Adhesive will treat 400 slides.
    3. Aminoalkylsilane Slide Adhesive is initially clear or light amber in color and may become cloudy and turn darker in color as it ages.
        1. Adhesive effectiveness will not diminish if these changes occur.
    4. Tissue section will strongly adhere to treated slide from first contact, position section carefully.
    5. To prevent formation of water blisters trapped between paraffin section and glass, drain and dry sectioned slides in a vertical position.

    1. See Procedure Notes #2 and #3.
  2. Mordant in preheated Bouin Fluid for one hour at 56-60°C or overnight at room temperature. Cool at room temperature for 5-10 minutes.
    1. Skip Step #3 if tissue was originally Bouin fixed.

       Microwave Modification:  See Procedure Note #4.

  1. Place slides in a plastic Coplin jar containing Bouin Fluid and microwave for 5 minutes at 60°C. Allow slides to sit an additional 10 minutes in solution.
  1. Wash well in running tap water; rinse in distilled water.
  2. Prepare fresh Weigert Iron Hematoxylin; combine and mix well.
    1. Solution A: Ferric Chloride, Acidified               20 ml
    2. Solution B: Hematoxylin 1%, Alcoholic           20 ml
  3. Stain slides in fresh Weigert Iron Hematoxylin for 10 minutes.
  4. Wash in running tap water for 10 minutes; rinse in distilled water.
    1. See Procedure Note #5.
  5. Place slides in Biebrich Scarlet-Acid Fuchsin Stain, Aqueous for 2 minutes.
  6. Rinse in distilled water.
  7. Place slides in Phosphomolybdic-Phosphotungstic Acid, Aqueous for 10 to15 minutes.

  9. Rinse in distilled water.
  10. Place slides in Acetic Acid 0.5%, Aqueous for 3 to 5 minutes.
  11. 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:

Collagen and mucin Blue
Muscle fibers, cytoplasm and keratin Red
Nuclei Blue/black

 

PROCEDURE NOTES:

  1. Using ammonium hydroxide to soak or face tissue blocks will alter the pH of tissue sections and greatly diminish trichrome staining.
  2. Drain staining rack/slides after each step to prevent solution carry over.
  3. Do not allow sections to dry out at any point during staining procedure.
  4. The suggested microwave procedure has been tested at Newcomer Supply using an “EB Sciences”, 850 watt microwave oven with temperature probe and agitation tubes.  This procedure is reproducible in our laboratory.  It is nonetheless a guideline and techniques should be developed for your laboratory which meet the requirements of your situation. Microwave devices should be placed in a fume hood or vented into a fume hood, according to manufacturer’s instructions, to prevent exposure to chemical vapors.
  5. If Weigert Iron Hematoxylin is not completely washed from tissue sections, nuclear and cytoplasmic staining may be compromised.
  6. If using a xylene substitute, closely follow the manufacturer’s recommendations for deparaffinization and clearing steps.
