Recombinant Mouse Leptin R

Leptin receptor, also known as LEPR, and CD295 (cluster of differentiation 295) is a single-transmembrane-domain receptor of the cytokine-receptor family.¹ 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.²
