Periodic Acid-Schiff Stain with Diastase
Use
The PAS-D (Periodic Acid-Schiff with Diastase) special stain is used in pathology to identify glycogen, mucopolysaccharides, and certain fungal organisms in tissue samples. Diastase treatment specifically breaks down glycogen, helping to differentiate it from other structures. This stain is commonly used in diagnosing glycogen storage diseases, fungal infections, and various disorders involving mucopolysaccharides.
