GMS Stain Kit with Periodic Acid

The Modified Gomori Methenamine-Silver Nitrate Stain (GMS Stain Kit) is intended for use in the histologic visualization of fungi, basement membrane and some opportunistic organisms such as Pneumocystis carinii. Periodic acid replaces traditional chromic acid as a less hazardous oxidation alternative. Background connective tissue may stain blacker in comparison with standard chromic acid oxidation.

P. carinii: Black
