PAS techniques are used to demonstrate polysaccharides, neutral mucosubstances and basement membranes primarily in tissue. It is an easy, reproducible stain that provides exceptional stain quality. Kit also includes diastase powder to enable demonstration of glycogen by performing PAS with diastase digestion. Protocols available for both procedures.

Stains up to 100 slides
