Sodium metabisulfite

Product Description

Component of Alcian Blue-P.A.S. and P.A.S. staining kits.

Available Options:


One of the most frequently used chemical methods in histology is P.A.S. staining. The P.A.S. staining is based on the oxidation reaction with the presence of periodic acid and Schiff’s reagent. Periodic acid makes the molecules containing glycol groups create aldehydes affected by Schiff’s reagent that stains them violet (magenta). This method is most commonly used in liver and muscle cells testing. Specific coloration is created by applying the P.A.S. method on unsubstituted polysaccharides, mucoproteins, glycoproteins, glycolipids and phospholipids. Combined with Alcian Blue in Alcian Blue-P.A.S. staining kit it can detect acidic mucosubstances (glycosaminoglycans).
