Anti-ODAPH antibodies are used in the immunodetection of the protein odontogenesis associated phosphoprotein. In humans, the canonical protein has a reported length of 130 amino acid residues and a mass of 15.6 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the placenta. ODAPH is believed to promote nucleation of hydroxyapatite. The ODAPH gene has been associated with the disease, Amelogenesis imperfecta. Synonyms for this target antigen include amelogenesis imperfecta type IIA4 and uncharacterized protein C4orf26. ODAPH gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some ODAPH antibodies may have been used in research and have associated citations. These antibodies are most commonly used in ELISA experiments, among other applications.
