ALCIAN BLUE/PAS STAIN KIT APPLICATIONS:

This stain differentiates between neutral and acidic mucosubstances. Acidic mucosubstances are stained with the Alcian Blue technique and neutral mucosubstances are stained by the PAS reaction.

All Newcomer Supply Stain Kits are designed to be used with Coplin jars filled to 40 ml following the staining procedure provided below. Some solutions in the kit may contain extra volumes.

ALCIAN BLUE/PAS STAIN KIT METHOD:

Fixation: 10% Neutral Buffered Formalin

Technique: Paraffin sections cut at 5 microns

Solutions: All solutions manufactured by Newcomer Supply

ALCIAN BLUE/PAS STAIN KIT PROCEDURE:

Deparaffinize sections thoroughly in three changes of xylene, then hydrate through graded ethyl alcohols to distilled water.
Place slides in Solution A, Acetic Acid, 3% Aqueous Solution for 3 minutes.
Place slides in Solution B, Alcian Blue Stain Solution, 1%, pH 2.5 for 30 minutes.
Wash slides in gently running tap water for 10 minutes, followed by a distilled water rinse.

ALCIAN BLUE/PAS STAIN KIT PROCEDURE NOTES:

This Schiff Reagent is stored at room temperature. There is no benefit to storing our product in the refrigerator.
Use care in handling. Schiff Reagent readily stains skin and is only removed through time and wear.
Formalin contamination will ruin Schiff Reagent, even prolonged exposure to formalin fumes will deactivate the solution.
Washing too long after Schiff Reagent can bleach the color out.

COMPLIMENTARY UNSTAINED POSITIVE CONTROL SLIDES:

Each kit comes with two complimentary unstained positive control slides to be used for the initial verification of staining techniques and reagents. We suggest running one slide along with your in-house positive control slide for the first run. Retain the second slide for further troubleshooting, if needed.
