Eosinophil
These micrographs show the cellular components of eosinophils. Note the bilobed nucleus with lobes connected by a thin region of chromatin. Like all granular leucocytes, eosinophils have both azurophilic (primary) granules and specific (secondary) granules. In eosinophils, the specific granules contain a large crystalloid body surrounded by an electron dense matrix. These granules stain intensely with eosin. The cytoplasm contains few other membranous organelles. 1000x, 10,000x

- Crystalloid bodies
The contents of the specific granules of eosinophils have powerful cytotoxic effects on protozoan and helminthic parasites. These granules stain intensely with eosin and contain a crystalloid body that is responsible for the refractivity of the granules seen by light microscopy.
