Overview
Leptin (aka OB protein, or Obesity factor protein) is a 16-kDa peptide hormone secreted from white adipocytes and implicated in the regulation of food intake and energy balance. Leptin provides the key afferent signal from fat cells in the feedback system that controls body fat stores.|Leptin (human), (recombinant) is produced in E.Coli as a single, non-glycosylated, polypeptide chain containing 146 amino acids and having a molecular mass of approximately 16 kDa. The Leptin protein is purified by proprietary chromatographic techniques.|Biological Activity is evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.
