Hematoxylin

Hematoxylin is a natural product. (In Vitro) :When exposed to air, Hematoxylin is oxidized to reddish brown hematein. When oxidized to its hematein form and combined with a mordant, usually a metal salt, Hematoxylin stains tissue sections a deep blue to black color depending on the staining method. By itself, Hematoxylin is also amphoteric in its hematein form; it is red at acid pH and blue at alkaline pH. Differentiation following Hematoxylin staining removes nonspecific staining.Hematoxylin treatment greatly alleviates Aβ42-induced cytotoxicity in SH-SY5Y cells. Hematoxylin is a potential agent against Aβ fibrillogenesis and cytotoxicity.The Hematoxylin and Eosin (H&E) stained tissue section is the cornerstone of anatomical pathology diagnosis. The H&E procedure stains the nucleus and cytoplasm contrasting colors to readily differentiate cellular components.
