Several staining techniques are used in histopathology: - Hematoxylin and Eosin (H&E) Staining: The most common technique, it distinguishes the nucleus (blue) from the cytoplasm (pink). - Special Stains: Such as Periodic Acid-Schiff (PAS) for carbohydrates, and Masson's Trichrome for collagen. - Immunohistochemistry (IHC): Uses antibodies to detect specific proteins in tissues, providing insights into molecular changes.
