| 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. |
