A cytochrome b with a midpoint oxidation-reduction potential of −245mV (cytochrome b-245) that is a major component of the microbicidal oxidase system of human neutrophil leucocytes has been identified in human eosinophils, monocytes and macrophages at concentrations similar to that found in human neutrophils. It was absent from a variety of other cells. This cytochrome is present in phagocytic leucocytes and probably plays an important part in the specialized activities of these cells.
