What are the Common Stains Used in Histopathology?
Different stains are used to highlight various cellular components. The most commonly used stain is Hematoxylin and Eosin (H&E), where hematoxylin stains cell nuclei blue, and eosin stains cytoplasm and extracellular matrix pink. Other stains include Periodic Acid-Schiff (PAS), which is used to detect polysaccharides like glycogen, and Masson's Trichrome, which differentiates between muscle fibers, collagen, and cytoplasm.
