||Leptin receptor, also known as LEPR, and CD295 (cluster of differentiation 295) is a single-transmembrane-domain receptor of the cytokine-receptor family. Leptin receptor exists in multiple forms with a common extracellular domain and a variable length cytoplasmatic portion. Leptin receptor may act as a negative regulator of Leptin activity and it may maintain a pool of available bioactive Leptin by binding and delaying its clearance from circulation. Leptin receptor is considered a physiological marker of primate fetal lung maturity.
||The predicted molecular weight of Recombinant Mouse Leptin R is Mr 120 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 150-170 kDa.
|State Of Matter:
||>97% by SDS Page and analyzed by silver stain.
||<0.1 ng per 1 µg as determined by the LAL method.
|Storage And Stability:
||This lyophilized protein is stable for six to twelve months when stored desiccated at -20°Cto -70°C.
