Description: The SN5c monoclonal antibody recognizes human CD10 (CALLA, NEP, enkephalinase, Neprilysin), which is a 100 kDa, type II cell surface glycoprotein. CD10 was shown to be the same molecule as neutral endopeptidase (NEP), or KII-NA. CD10 is a zinc-dependent metallopeptidase acting on substrates such as endothelin, glucagon, gastrin, neurotensin and bradykinin. CD10 is involved in the regulation of chemotactic and inflammatory processes involving neutrophils. In B cells, CD10 regulates stromal cell-dependent B lymphopoiesis and its expression has been reported on mature germinal center B cells. CD10 expression is also found on normal donor granulocytes and bone marrow stromal cells.
