Clonality Monoclonal
Immunogen Cultured macrophages.
The F4/80 antigen is a 125 kD extracellular membrane protein sensitive to 2-Mercaptoethanol.
Specificity This antibody is useful for the detection of major subpopulations of resident tissue macrophages. The antigen expression increases upon maturation of macrophage precursors in bone marrow and blood as well as in ontogeny.
This clone BM8 is the only macrophage marker that is able to distinguish non-destructive from destructive inflammation processes in the pancreas and has been shown to be a unique histological marker of the progression from peri-insulitis to ß-cell destruction and diabetes in a mouse diabetes model.
Antigen Distribution on Tissue and Isolated Sections: The antigen is detected on tissue fixed macrophages in all organs tested so far (spleen, lymph nodes, thymus, liver, skin). It is also present on Langerhans cells in the skin and Kupffer cells in the liver. In complete Freund's adjuvant induced granulomas the antigen is expressed by inflammatory macrophages, but is absent from epitheloid cells.
The antigen is expressed in vitro on over 80% of M-CSF stimulated bone marrow derived macrophages, after a few days of culture. It is absent from granulocytes, lymphocytes and thrombocytes.

Gene Name Mus musculus adhesion G protein-coupled receptor E1 (Adgre1)
Background F4/80 antigen is a 160 kDa cell surface glycoprotein that is a member of the EGF TM7 family of proteins which shares 68% overall amino acid identity with human EGF module containing mucin like hormone receptor 1 (EMR1). Expression of F4/80 is heterogeneous and is reported to vary during macrophage maturation and activation. The F4/80 antigen is expressed on a wide range of mature tissue macrophages including Kupffer cells, Langerhans, microglia, macrophages located in the gut lamina propria, peritoneal cavity, lung, thymus, bone marrow stroma and macrophages in the red pulp of the spleen. F4/80 expression has also been reported on a subpopulation of dendritic cells but is absent from macrophages located in T cell areas of the spleen and lymph node. The ligands and biological functions of the F4/80 antigen have not yet been determined but recent studies suggest a role for F4/80 in the generation of efferent CD8+ve regulatory T cells.
