Eosinophil:

	The characteristic red-staining eosinophil granules (Wright's stain) represent a number of unique constituents.
	The distinctive feature of the eosinophil granule is its crystalline core consisting of an arginine-rich protein (major basic protein) with histaminase activity.
	Eosinophil granules also contain a unique eosinophil peroxidase that catalyzes the oxidation of many substances by hydrogen peroxide and may facilitate killing of microorganisms.
