Periodic Acid-Schiff (PAS) Kit

The Periodic Acid-Schiff (PAS) reaction is a fundamental histochemical technique for demonstrating carbohydrate-rich macromolecules in tissue sections. The kit stains glycogen, mucins, glycoproteins, and proteoglycans a brilliant magenta color. Essential for diagnosing glycogen storage diseases, identifying fungal organisms, highlighting basement membranes, and detecting mucin-producing tumors. The PAS technique can be combined with diastase digestion to specifically confirm glycogen presence. This versatile stain is indispensable in renal pathology, liver biopsies, gastrointestinal studies, and dermatopathology.
