Peroxisome proliferator-activated receptors (PPARs) are members of the nuclEAr receptor family of ligand activated transcription factors that heterodimerizes with retinoic acid-like receptors to regulate gene expression and differentiation.1 The PPAR family of nuclEAr hormone receptors consists of three subtypes encoded by separate genes: PPAR, PPAR (also referred to as hNUC1, PPAR, or FAAR), and PPAR. Among them PPAR is the most widely studied and has been implicated in the pathology of numerous disEAses including obesity, diabetes, atherosclerosis, and cancer.2 PPAR is primarily expressed in adipose tissue and to a lesser extent in the colon, immune system, and the retina.3 PPAR FL (human recombinant from E. coli) purity was determined using gel electrophoresis followed by coomassie staining.Technical InformationSynonymsPeroxisome Proliferator-activated Receptor Full LengthPurity80% estimated by SDS-PAGESourcehuman recombinant N-terminal His-tagged protein expressed in E. coliMW~60 kDaFormulationA solution in 20 mM Tris HCl, pH 8.0, containing 250 mM KCl, 20% glycerol, 5 mM DTT, and 0.5 mM EDTAUniProt Accession P37231
