PAS Staining Kit is used to demonstrate the presence of glycogen in tissue. PAS-positive reticular fibers, basement membrane, fungus, and neutral mucopolysaccharides are also detected. PAS Staining Kit may also be used to aid in distinguishing a PAS-positive, secreting adenocarcinoma from undifferentiated PAS-negative squamous cell carcinoma. PAS Staining Kit uses Periodic Acid to oxidize glycols to aldehydes. Schiff's Reagent forms a colorless dialdehyde compound that is transformed to the colored final staining of glycol-containing cellular components. PAS staining in tissue sections and digestion with diastase is useful as an aid in the diagnosis of glycogen storage disease. The PAS Staining Kit stains glycogen bright magenta, with cell nuclei staining light purple.
Note: Open only on Schiff's Reagent vial at a time. Each vial is stable for ONE month after opening.
