Anti-COX6A2 antibodies are used in the immunodetection of the protein cytochrome c oxidase subunit 6A2. In humans, the canonical protein has a reported length of 97 amino acid residues and a mass of 10.8 kDa. Its subcellular localization is in the mitochondria. It is notably expressed in the heart and muscle. A member of the Cytochrome c oxidase subunit 6A protein family, COX6A2 is a known component of the cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain which drives oxidative phosphorylation. The COX6A2 gene has been associated with the disease, Mitochondrial complex IV deficiency. Synonyms for this target antigen include COXVIAH, COXVIa-M, MC4DN18, cytochrome c oxidase subunit 6A2, mitochondrial, COX VIa-M, and COX6AH. COX6A2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some COX6A2 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.
