Anti-BDH2 antibodies are used in the immunodetection of the protein 3-hydroxybutyrate dehydrogenase 2. In humans, the canonical protein has a reported length of 245 amino acid residues and a mass of 26.7 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the liver. A member of the Short-chain dehydrogenases/reductases (SDR) protein family, BDH2 is known to be involved with epithelial cell differentiation. Synonyms for this target antigen include (R)-beta-hydroxybutyrate dehydrogenase, 3-hydroxybutyrate dehydrogenase, type 2, 4-oxo-L-proline reductase, R-beta-hydroxybutyrate dehydrogenase, and dehydrogenase/reductase SDR family member 6. BDH2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of BDH2 antibodies have been mentioned in research publications and have associated citations. ELISA, Flow Cytometry, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
