Specificity
- This antibody Clone PM-2K, together with X-4 (BM4035) and X-14 (BM4036), forms a particular group of macrophage specific antibodies which were classified at the V Leukocyte Typing Workshop held in Boston in 1993. PM-2K recognises tissue macrophages and macrophages in proliferative disorders of macrophages. PM-2K is one of the markers that, being negative on dendritic cells, can differentiate between macrophages and dendritic cells. Under non-reducing conditions PM-2K recognizes an antigen of 150 kDa (Western blot) which has been shown to be on cytoplasmic membranes. Antigen Distribution: Isolated Cells: Positive on >90 % of alveolar macrophages, and on 10 % of adherent peritoneal cells after 1 day culture. Negative on dendritic cells, on freshly isolated blood monocytes or peritoneal cells, and on bone marrow cells including monocytes, myelomonocytic precursors and megakaryocytes. Tissue Sections: PM-2K stains most tissue macrophages in lymphoreticular organs such as thymus, spleen, lymph node and tonsil. It is positive on Kupffer cells of the liver, alveolar macrophages and macrophages in the interstitial tissues of the kidney, pancreas and many other organs. In Gaucher's disease multicentric reticulohistiocytosis and malignant histiocytosis proliferating macrophages are positive. In MFH infiltrating macrophages are stained but not tumour cells. Some bone stromal cells but not osteoclast-like multinucleated giant cells are stained in GCT. Microglial cells, osteoclasts and dendritic cells such as Langerhans cells, interdigitating cells and follicular dendritic cells are negative.
