Anti-COX4 antibodies enable researchers to detect and measure the COX4 antigen in biological samples. This target is a reported synonym of the COX4I1 gene, which encodes cytochrome c oxidase subunit 4I1. This protein is known to function in electron transport, among other biological roles. The human version of COX4 has a canonical amino acid length of 169 residues and a protein mass of 19.6 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. COX4 is a member of the Cytochrome c oxidase IV protein family. A number of COX4 antibodies have been mentioned in research publications and have associated citations. Indicated applications for the antibodies listed below include ELISA and Western Blot.
