Hematoxylin & Eosin Stain
Use
Hematoxylin and eosin (H&E) is one of the most commonly used special stains in histopathology for routine examination of tissue sections. Hematoxylin stains cell nuclei a blue to purple color, while eosin stains the cytoplasm and extracellular matrix in shades of pink, allowing pathologists to examine tissue morphology and structure. This stain is crucial in identifying various pathological conditions, including tumors, infections, and inflammatory diseases, making it a fundamental tool in diagnostic pathology.
