Clone: 25F9

Product Details

Specificity: Monoclonal antibody 25F9 is associated with fully differentiated tissue macrophages both in normal and diseased tissues, particularly also in the late stage of an inflammation. Antigen Distribution Isolated Cells: Absent on freshly isolated monocytes and other blood cells, present on 40-50 % of human monocytes after 6-7 days in culture, also positive on some melanoma and carcinoma cell lines. Tissue Sections: Kupffer cells, histiocytes (skin), macrophages of the thymus, in the germinal centres of lymph nodes and spleen, in mamma carcinoma, melanoma, osteocarcinoma and gastric cancer, eczema, sarcoidosis, BCG granuloma, synovial lining cells, tuberculoid leprosy: no expression in lepromatous leprosy. Antibody BM4022 reacts with Human Mature Macrophages and Monocytes. Other Species (tested so far): Subpopulation of macrophages in Rhesus monkey, reactive with pig alveolar macrophages and Kupffer cells.

Cross-Reactivity (Details): Species reactivity (tested):Human.

Purification: Affinity Chromatography.

Immunogen: Cultured human monocytes. Remarks: The antigen is a 86 kDa membrane protein, the epitope has not been further characterized.

Isotype: IgG1

Application Details

Application Notes: Immunohistochemistry on Frozen Sections: 1 μg/mL (1/200). Immunohistochemistry on Paraffin Sections: 2 μg/mL (1/100). Proteinase K pretreatmentfor antigen retrieval recommended. Suggested Positive Control: Human tonsil. The antibody is suitable for staining macrophages from bronchial lavage fluids and similartechniques. It is very useful for macrophage phenotyping, particularly for the classificationof late inflammatory stages (together with the anti calprotectin clone 27E10 and the antiCD163 clone 5C6-FAT). It is used in tissue sections and in smears, for the characterization of tumorous tissues andthe monitoring of macrophage cell cultures.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.
