Large lymphocyte and monocyte in peripheral blood smear (human) | Stain: May-Grnwald-Giemsa (MGG). The large lymphocyte (1) has a slightly condensed nucleus and the cytoplasm contains some fine azurophilic granules, and is therefore sometimes called large granular lymphocyte (LGL) or killer cell. The monocyte (2) is generally larger than the lymphocyte with a roun... | Poja Histology Collection - Blood & Bone Marrow Subset | |

Large lymphocyte in peripheral blood smear (human) | Stain: May-Grnwald-Giemsa (MGG). The large lymphocyte has a dense chromatin structure and a large transparent cytoplasm with some granules (→). (On the contrary a monocyte exposes a more transparent nucleus and a slightly greyish cytoplasm). | Poja Histology Collection - Blood & Bone Marrow Subset | |

Late band-form of neutrophilic granulocyte (peripheral blood, human) | Electron microscopy. Band forms (9-12 μm) are the earliest stages of the motile two-lobed granulocytes. The horseshoe shaped nucleus (3) is irregularly and indicates progressing lobulation. The neutrophil contains many granules of varying sizes and densities. On base of routine electron microscopy ... | Poja Histology Collection - Blood & Bone Marrow Subset | |

Leukocyte Alkaline Phosphatase (LAP/NAP score) in peripheral blood smear (human) | Stain: Alkaline phosphatase staining (Ackerman). In mature neutrophils granules contain alkaline phosphatase. In eosinophils no alkaline phosphatase activity is present. A considerable number of brown stained neutrophils can be indicative for a patient with infection (leukemoid reaction, A).
