There are several types of histological stains, each serving different purposes:
1. Routine Stains: These include H&E, which provides a general overview of tissue architecture. 2. Special Stains: These target specific tissue elements, such as Periodic Acid-Schiff (PAS) for glycogen and mucopolysaccharides, and Masson's Trichrome for collagen fibers. 3. Immunohistochemical Stains: These use antibodies to detect specific proteins, offering insights into the presence and localization of particular molecules within tissues.
