Anti-PDHE1-B antibodies enable researchers to detect and measure the PDHE1-B antigen in biological samples. This target is a reported synonym of the PDHB gene, which encodes pyruvate dehydrogenase E1 subunit beta. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of PDHE1-B has a canonical amino acid length of 359 residues and a protein mass of 39.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include E1beta, PDHBD, and PDHE1-B.
