Part # 4130B98/Set $346.00

PRODUCT SPECIFICATIONS:

Tissue:  Positive staining animal liver.

Fixation: Formalin 10%, Phosphate Buffered (Part 1090).

Section/Glass: Paraffin sections cut at 4 microns on Superfrost™ Plus slides.

Quality Control Stain:  Rhodanine quality control stained slide(s) included.

Reactivity: Guaranteed product specific reactivity for one year from date of receipt. Revalidate after one year to verify continued reactivity. 

Storage: 15-30°C in a light deprived and humidity controlled environment.

Before using unstained control slides, review the enclosed stained slide(s) to ensure that this tissue source is acceptable for testing needs.

 

PRODUCT DESCRIPTION:

The enclosed positive control slides are intended to verify histological techniques and reagent reactivity. The intended use is for the qualitative purpose of determining positive or negative results, and not intended for any quantitative purpose. The positive control sections are produced from animal tissues under carefully controlled conditions.  Quality control measures are used to deliver control slides that are as consistent as possible. 

 

CONTROL SLIDE VALIDATION:

With Copper, Rhodanine Stain Kit: Part 9113A Individual Stain Solution
Solution A: Rhodanine Stock Stain 0.2%, Alcoholic 50 ml Part 10531
Solution B: Hematoxylin Stain, Mayer Modified 250 ml Part 1202

APPLICATION:

Newcomer Supply Copper, Animal Control Slides are for the positive histochemical detection of copper in tissue sections.

 

PRESTAINING PREPARATION:

  1. Heat dry sections in oven according to your laboratory protocol.
  2. Prepare Working Rhodanine Solution; combine and mix well.
    1.   Shake Solution A: Rhodanine Stock Stain 0.2%, Alcoholic well before each use.
    2.   Solution A: Rhodanine Stock Stain 0.2%, Alcoholic    3 ml
    3.   Distilled Water                                                          47 ml

 

NEWCOMER SUPPLY VALIDATION PROCEDURE:

  1. 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 #1 and #2.
  2. Stain in Working Rhodanine Solution (Step #2) at 60°C for 1-2 hours or at 37oC for 18 hours.

        Microwave Modification:  See Procedure Note #3.

  1. Place slides in a plastic Coplin jar containing Working Rhodanine Solution and microwave for 6 minutes at 70°C.
  1. At the end of incubation (for both oven and microwave), to avoid unwanted slide precipitate, pour off warm Working Rhodanine Solution into a second Coplin jar; reserve and set aside.
  2. Rinse slides well in several changes of distilled water.
  3. Check positive control slide microscopically to determine adequate copper/reddish brown development.
    1. Return slides to reserved Working Rhodanine Solution if additional incubation is required.
  4. Prepare dilute Mayer Hematoxylin Stain Solution directly before use; combine and mix well:
    1.   Solution B: Hematoxylin Stain, Mayer Modified         20 ml
    2.   Distilled Water                                                           20 ml
  5. Stain in dilute Mayer Hematoxylin Stain Solution for 10 minutes.                      
  6. Rinse in distilled water.
  7. Rinse in Solution C: Sodium Borate 0.5%, Aqueous; 2-3 quick dips.
  8. Rinse well in distilled water.
  9. 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:

Copper Copper/reddish brown
Nuclei Light blue

  

PROCEDURE NOTES:

  1. Drain slides after each step to prevent solution carry over.
  2. Do not allow sections to dry out at any point during procedure.
  3. The suggested microwave procedure has been tested at Newcomer Supply.  This procedure is a guideline and techniques should be developed for use in your laboratory.
  4. If using a xylene substitute, closely follow the manufacturer’s recommendations for deparaffinization and clearing steps.
