This antibody recognises the Mouse F4/80 antigen, a 160 kDa glycoprotein expressed by murine macrophages. The antibody binds to Macrophages from different sites including the peritoneal cavity, lung, spleen and thymus, to blood monocytes and to macrophages derived from bone marrow precursors in culture. The antigen is not expressed by lymphocytes or polymorphonuclear cells.

F4/80 antigen is a 160 kD 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.Synonyms: Cell surface glycoprotein EMR1, EMR1 hormone receptor, Emr1, Gpf480
