Applications
UsesColorant in inks, biological stains.
UsesHematoxylin 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.
General DescriptionWhite to yellowish crystals that redden on exposure to light.
DescriptionHematoxylin is a blue nuclear counterstain for use in immunohistochemical assays. It yields crisp staining detail with superior contrast when used in conjunction with SignalStain® DAB Substrate Kit
