Hematoxylin and Eosin are two commonly used dyes in histology and pathology. They are often used together to stain tissue samples, allowing for the detailed examination of cellular structures under a microscope. Hematoxylin stains cell nuclei a blue-purple color, whereas Eosin stains the extracellular matrix and cytoplasm pink. This combination is widely referred to as the H&E stain.
