Anti-NDUFS2 antibodies are used in the immunodetection of the protein NADH:ubiquinone oxidoreductase core subunit S2. In humans, the canonical protein has a reported length of 463 amino acid residues and a mass of 52.5 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Complex I 49 kDa subunit protein family, NDUFS2 is reported to be a core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) which catalyzes electron transfer from NADH through the respiratory chain, using ubiquinone as an electron acceptor. Synonyms for this target antigen include MC1DN6, NADH dehydrogenase [ubiquinone] iron-sulfur protein 2, mitochondrial, CI-49kD, and CI-49. NDUFS2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of NDUFS2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
