Ready-to-use ELISA kits are available for the detection of cytochrome c oxidase subunit Va, an alias of the protein, cytochrome c oxidase subunit 5A. The official gene symbol is COX5A. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 16.8 kDa and length of 150 residues, is reported to be mitochondrial. It is a member of the Cytochrome c oxidase subunit 5A family and may be known by other names, including: VA, COX-VA, cytochrome c oxidase subunit Va, cytochrome c oxidase polypeptide mitochondrial, cytochrome c oxidase polypeptide Va, and cytochrome c oxidase subunit 5A mitochondrial.
