Anti-OGFR antibodies are used in the immunodetection of the protein opioid growth factor receptor. In humans, the canonical protein has a reported length of 677 amino acid residues and a mass of 73.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the heart and liver, moderately in skeletal muscle and kidney and to a lesser extent in the brain and pancreas. A member of the Opioid growth factor receptor protein family, OGFR is a known receptor for opioid growth factor (OGF), also known as Met-enkephalin. Synonyms for this target antigen include protein 7-60 and zeta-type opioid receptor. OGFR gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. A number of OGFR antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
