Anti-NDUFB2 antibodies are used in the immunodetection of the protein NADH:ubiquinone oxidoreductase subunit B2. In humans, the canonical protein has a reported length of 105 amino acid residues and a mass of 12.1 kDa. Its subcellular localization is in the mitochondria. A member of a the Complex I NDUFB2 subunit protein family, NDUFB2 is reported to be an accessory subunit the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be involved in catalysis. Synonyms for this target antigen include CI-AGGG, NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 2, mitochondrial, NADH dehydrogenase (ubiquinone) 1 beta subcomplex, 2, 8kDa, NADH-ubiquinone oxidoreductase AGGG subunit, and AGGG.
