hematoxylin and eosin stain

Hematoxylin and eosin (H&E) stain is a common technique used in pathology to make tissue samples visible under a microscope. Hematoxylin binds to acidic components like cell nuclei, staining them a deep blue or purple, highlighting genetic material. Eosin attaches to basic components such as cytoplasm and connective tissue, giving them a pink or orange hue. This contrast helps pathologists differentiate various cell types and structures within tissues, aiding in diagnosing diseases. Overall, H&E staining provides a detailed overview of tissue architecture, making microscopic examination more informative and insightful.
