ECM-1/Secretory Component P85 Antibody (SC05) Summary

Immunogen
Partially purified ECM1 from human colostrum was used as immunogen to generate the antibody (Bartek, 1989).
Localization
Cell surface and cytoplasmic
Specificity
This MAb reacts with a reduction-resistant epitope present in both free and SIgA bound Secretory Component. It does not react with the cell lines lacking secretory component. The antibody is useful for studying the distribution and level of both free and bound secretory component. Secretory component is differentially expressed in epithelium, and the antibody is a popular marker for identifying subpopulations of epithelial cells and epithelial differentiation. The Secretory component antibody is a useful research tool for studying mucosal immunity, inflammation, remodeling, differentiation and tumorigenesis, all processes associated with differential secretory component expression.

Background

Secretory component is an ~80 kDa glycoprotein important in mucosal immunity. Secretory component is the extracellular cleaved ectodomain of the polymeric immunoglobulin (Ig) receptor (pIgR) which transports Igs across mucosal membranes into secretions (reviewed in Johansen, 2011). IgA is the main immunoglobulin in secretions and pIgR is highly expressed in intestinal epithelial cells (ECs). Dimeric IgA (dIgA) manufactured by antibody producing plasma cells in the intestinal lamina propria binds to pIgR at the basolaterial membrane surface of ECs. pIgR-dIgA complexes are internalized and transcytosed across ECs to the apical surface. Secretory component is then proteolytically cleaved off from the pIgR and released into the lumen together with dIgA. Secreted IgA (SIgA) consists of dIgA + secretory component. SIgA protects the mucosa from microbial invasion, and bound Secretory component enhances immune function by inhibiting SIgA proteolytic degradation. The SC05 antibody clone reacts with both free and bound secretory component (Bartek, 1989); it does not react in western blots of cell lines that lack secretory component. The antibody is useful for studying the distribution and level of both free and bound secretory component. Secretory component is differentially expressed in epithelium, and the antibody is a useful marker for identifying subpopulations of epithelial cells and epithelial differentiation (Fichorova, 1997 & 1998). Secretory component antibodies have also been part of antibody marker panels for differential identification of glandular carcinomas (Brown, 1993; Harris, 1981; Kalhounou, 2010). The Secretory component antibody is a useful research tool for studying mucosal immunity, inflammation, remodeling, differentiation and tumorigenesis, all processes associated with differential secretory component expression (Bartek, 1990; Johansen, 2011). Since the presence of secretory component implies immunological function, the antibody can help identify cells regulating immunological processes (Fichorova, 1999). The antibody can also be used to indirectly assess SIgA expression since SIgA contains bound secretory component (Vancikoa, 2003). The secretory component antibody SC05 clone is also known as clone COMPO2 (Tang, 1985) in the published literature.
