General description
Hemin is a pro-oxidant, hemolysis derived-product. It is essential for the growth of heme-deficient organisms such as trypanosomatids.

It is present as a key ingredient compound in common anaerobic growth media, such as Brucella broth, Thioglycolate broth and Reinforced Clostridial Medium.
