Anti-OCSTAMP antibodies are used in the immunodetection of the protein osteoclast stimulatory transmembrane protein. In humans, the canonical protein has a reported length of 566 amino acid residues and a mass of 61.6 kDa. Its subcellular localization is in the membrane. OCSTAMP is a suspected cell surface receptor that plays a role in cellular fusion and cell differentiation. Synonyms for this target antigen include transmembrane protein C20orf123. OCSTAMP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These OCSTAMP antibodies are widely used in Western Blot experiments, among other applications.
