Anti-OKT antibodies are used in antigen-specific immunodetection in biological samples. The target OKT is a known alias name of the protein ornithine aminotransferase, encoded by the OAT gene in humans. This 439-amino acid residue protein is known to catalyze the reversible interconversion of L-ornithine and 2-oxoglutarate to L-glutamate semialdehyde and L-glutamate. It is localized to the mitochondria of the cell. It is reported to be expressed in many tissues, such as the duodenum and small intestine. Other synonyms for OKT include GACR, HOGA, and OATASE. Indicated applications for OKT antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
