Hematoxylin is a type of basic dye used in histology and pathology to stain cell nuclei. It is commonly used in combination with eosin, a pink acidic dye, in the Hematoxylin and Eosin (H&E) staining technique, which is one of the most widely used staining methods in histology. Hematoxylin stains acidic structures, such as cell nuclei, blue-purple, while eosin stains basic structures, such as cytoplasm, pink. This staining method allows for the visualization of cellular structures and tissue architecture under a microscope.
