Anti-OXTR antibodies are used in the immunodetection of the protein oxytocin receptor. In humans, the canonical protein has a reported length of 389 amino acid residues and a mass of 42.8 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, Oxtr is a known receptor for oxytocin. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include OT-R and OTR. OXTR gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 60 citations in the literature describe the use of Oxtr antibodies in research. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
