More specifically, hemochromogen may refer to a derivative of hemoglobin in which heme is combined with a globin modified by the action of a strong alkali. This compound is useful in determining whether a stain is blood because it can be formed from an old blood stain and because, of all blood pigments, it can be identified in the greatest dilution.
