There are a number of ELISA Kits available for the measurement of Peroxisome proliferator-activated receptor alpha, another term for the human protein, peroxisome proliferator activated receptor alpha. Other synonyms may include: PPAR-alpha, nuclear receptor subfamily 1 group C member 1, peroxisome proliferative activated receptor alpha, peroxisome proliferator-activated nuclear receptor alpha variant 3, PPAR, PPARalpha, and hPPAR. It is encoded by the PPARA gene to yield a protein 468 amino acids in length and 52.2 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the Nuclear hormone receptor family, NR1 subfamily. Versions of Peroxisome proliferator-activated receptor alpha are present in other organisms, including: Mouse, Rat.
