Anti-Rdhs antibodies enable researchers to detect and measure the Rdhs antigen in biological samples. This target is a reported synonym of the SDR9C7 gene, which encodes short chain dehydrogenase/reductase family 9C member 7. This protein is known to function in metabolic processes, among other biological roles. The human version of Rdhs has a canonical amino acid length of 313 residues and a protein mass of 35.3 kilodaltons. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include short-chain dehydrogenase/reductase family 9C member 7 and orphan short-chain dehydrogenase / reductase.
