Certain histological stains are more susceptible to precipitate formation:
1. Hematoxylin: Often used in H&E staining, hematoxylin can form precipitates if not properly filtered or if the pH is not adequately controlled. 2. Silver Stains: Used for detecting reticular fibers and certain microorganisms, silver stains can form precipitates if the silver solution is not freshly prepared or if contaminants are present. 3. Trichrome Stains: These stains, used to differentiate between collagen and muscle fibers, can form precipitates if the reagents are not mixed well or if the pH is incorrect.
