Neutrophilic granulocyte and monocyte in peripheral blood smear (human)

Stain: May-Grnwald-Giemsa (MGG). (1) the neutrophil (12-15 μm) shows a dark-stained partly lobulated nucleus with the smaller lobe connected by a fine strand of chromatin to the larger nuclear part. The cytoplasm reveals very faintly small azurophilic (primary) granules. (2) the monocyte (12-20 μm) contains a large light-stained nucleus with a characteristic indentation with a distinct nucleolus in an light-stained apparently empty cytoplasm as the small primary or azurophilic granules are hardly visible.
