Anti-OXT antibodies are used in the immunodetection of the protein oxytocin/neurophysin I prepropeptide. In humans, the canonical protein has a reported length of 125 amino acid residues and a mass of 12.7 kDa. It has been described to be a secreted protein. It is notably expressed in the hypothalamus and ovary. A member of the Vasopressin/oxytocin protein family, OXT is known to be involved with cardiac tissue development. Synonyms for this target antigen include OT-NPI, OXT-NPI, oxytocin-neurophysin 1, neurophysin I, oxytocin, prepro- (neurophysin I), and OT. OXT gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of OXT antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
