Immunogen | Mouse lymph node stroma. Antigen, epitope: The antigen is a (glyco-)protein of 140kDa m.w. which is located within the cytoplasm and on the cell surface. The epitope has not been further characterized. |
Specificity | This antibody clone MOMA-2 is a useful marker for the broad detection of monocytes and macrophages in all mouse strains. In combination with the anti F4/80 marker BM8 it allows a precise characterisation of tissue fixed macrophages in various organs. The antibody stains a mature macrophage subset, monocytes and a few precursors in bone marrow. Dendritic cells show low to intermediate expression. The staining shows close correlation with expression of acid phosphatase in tissue sections. MOMA-2 is predominantly expressed in the cytoplasm, but is also present on the cell surface. Antigen Distribution Isolated Cells: In the cytospin preparation of thioglycollate stimulated peritoneal exudate cells MOMA-2 detects an antigen as distinct cytoplasmic spots. MOMA-2 detects monocytes of the peripheral blood and a subpopulation of bone marrow cells. Tissue Sections: MOMA-2 detects typical tissue macrophages as does the anti F4/80-specific clone BM8 (pan macrophage marker). However, different staining patterns are visible as shown below. The most predominant difference can be observed in T-cell areas and follicles of peripheral lymphoid organs where the anti F4/80 clone BM8 is negative. |
