Anti-osteomodulin antibodies are used for the immunodetection of the protein encoded by the OMD gene. In humans, the canonical protein has a reported length of 421 amino acid residues and a mass of 49.5 kDa. Its subcellular localization is in the extracellular matrix and is secreted. It is reported to have bone specific expression. A member of the Small leucine-rich proteoglycan (SLRP) protein family, it is believed to be implicated in biomineralization processes. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include SLRR2C, KSPG osteomodulin, keratan sulfate proteoglycan osteomodulin, osteoadherin proteoglycan, and OSAD. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of osteomodulin antibodies have been mentioned in research publications and have associated citations. ELISA and Western Blot are common applications for these antibodies.
