Anti-ECM1 antibodies are used in the immunodetection of the protein extracellular matrix protein 1. In humans, the canonical protein has a reported length of 540 amino acid residues and a mass of 60.7 kDa. Its subcellular localization is in the extracellular matrix and is secreted. Up to 4 different isoforms have been reported for this protein. It is reported to be expressed in breast cancer tissues. ECM1 is known to be involved in endochondral bone formation as negative regulator of bone mineralization. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include secretory component p85, testicular tissue protein Li 61, and URBWD. ECM1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ECM1 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
