Do not aliquot the antibody. Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity CD109 Antibody recognizes endogenous levels of total CD109 protein. Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly653 of human CD109 protein. Antibodies are purified by protein A and peptide affinity chromatography. Background CD109 is a glycosylphosphatidylinositol (GPI)-linked glycoprotein that belongs to the alpha2-macroglobulin family of thioester containing proteins (1). CD109 is associated with TGF-beta receptor I (TbRI) and inhibits TGF-beta signaling (2,3). Cleavage of CD109 at its Furin cleavage site results in the release of its large amino-terminal domain, which then binds to the TGF-beta receptor I to inhibit TGF-beta signaling (4-7). CD109 is expressed on a subset of CD34+ bone marrow cells and mesenchymal stem cells, activated platelets, activated T cells, endothelial cells, and a wide variety of tumors (8-10). Elevated CD109 expression has been considered a diagnostic/prognostic marker for several types of cancers (11-14).
