Description

CAS: 517-28-2 | C16H14O6 | 302.28 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
