Recombinant Human Leptin
Induced proliferation of Baf/3 cells for Leptin. Cell proliferation was measured to calculate the ED50.
Non-reducing (-) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue, 1 μg of protein was loaded. Human Leptin has a predicted Mw of 16.2 kDa.

Leptin is a hormone that is produced by adipose tissue and plays critical roles in the physiologic regulation of body weight. Leptin acts through the leptin receptor (LEPR) to regulate adipose mass by inhibiting hunger and balancing energy usage. Leptin mutations cause severe hereditary obesity and hypogonadism in rodents and humans. Leptin also has thermogenic actions, regulates enzymes of fatty acid oxidation, and is involved in hematopoiesis, angiogenesis, wound healing, inflammation, and immune responses.Activity Assay
Human Leptin is fully biologically active when compared to standard. The activity is determined by the ability to induce Baf/3 cells proliferation.AA Sequence
