Macrophages (Haematopoiesis associated) Mouse Monoclonal Antibody [Clone ID: 25F9]

Specifications

Product Data
Clone Name	25F9
Applications	IHC
Recommend Dilution	Immunohistochemistry on Frozen Sections: 0.25 μg/ml (1/800). Immunohistochemistry on Paraffin Sections: 0.5 μg/ml (1/400). Proteinase K pretreatment for antigen retrieval recommended. Suggested Positive Control: Human tonsil. The antibody is suitable for staining macrophages from bronchial lavage fluids and similar techniques. It is very useful for macrophage phenotyping, particularly for the classification of late inflammatory stages (together with the anti calprotectin clone 27E10 and the anti CD163 clone 5C6-FAT). It is used in tissue sections and in smears, for the characterization of tumorous tissues and the monitoring of macrophage cell cultures.
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Immunogen	Cultured Human monocytes.
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.
Formulation	PBS, pH 7.2 State: Purified State: Lyophilized purified Ig fraction Stabilizer: 5 mg/ml BSA Preservative: 0.05% Kathon CG
Reconstitution Method	Restore with 0.5 ml distilled water.
Concentration	0.2 mg/ml
Purification	Affinity Chromatography
Conjugation	Unconjugated
Storage Condition	Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing.
