Hematoxylin is a nuclear stain with a deep blue-purple color. It is used as a counterstain for immunohistochemical or hybridization procedures that use colorimetric substrates (e.g. alkaline phosphatase or peroxidase.)
It is a component of one of the most widely used histology stains: the H&E stain (Hematoxylin and Eosin stain).
