Anti-NAD(P)H quinone dehydrogenase 2 antibodies enable researchers to detect and measure the NAD(P)H quinone dehydrogenase 2 antigen in biological samples. This target is a reported synonym of the NQO2 gene, which encodes N-ribosyldihydronicotinamide:quinone reductase 2. The human version of NAD(P)H quinone dehydrogenase 2 has a canonical amino acid length of 231 residues and a protein mass of 25.9 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the kidney and testis. NAD(P)H quinone dehydrogenase 2 is a member of the NAD(P)H dehydrogenase (quinone) protein family.
