3.Application 

Hematoxylin and eosin together make up Hematoxylin and eosin stain, one of the most commonly used stains in histology. Metal-haematein complexes are used to stain cell nuclei prior to examination under a microscope. Structures that stain with iron- or aluminum-haematein are often called basophilic, even though the mechanism of the staining is different from that of staining with basic dyes.
