Ready-to-use ELISA kits are available for the detection of pyruvate dehydrogenase E1 alpha 2, an alias of the protein, pyruvate dehydrogenase E1 alpha 2 subunit. The official gene symbol is PDHA2. The protein, with a mass of 42.9 kDa and length of 388 residues, is reported to be mitochondrial. It may be known by other names, including: PDHAL, pyruvate dehydrogenase alpha 2, pyruvate dehydrogenase (lipoamide) alpha 2, PDHE1-A type II, and pyruvate dehydrogenase E1 component subunit alpha testis-specific form mitochondrial.
