Anti-ORM2 antibodies are used in the immunodetection of the protein orosomucoid 2. In humans, the canonical protein has a reported length of 201 amino acid residues and a mass of 23.6 kDa. It has been described to be a secreted protein. It is notably expressed by the liver and secreted in plasma. A member of the Lipocalin protein family, ORM2 is known to function as transport protein in the blood stream. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include AGP-B', AGP2, alpha-1-acid glycoprotein 2, AGP 2, OMD 2, alpha-1-acid glycoprotein, type 2, and AGP-B. ORM2 gene orthologs have been reported in the mouse, rat and chicken species. Some ORM2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
