Biological activity
Measured by its ability to inhibit Leptin-dependent proliferation of BaF3 mouse pro-B cells transfected with rhLEPR-Fc. The ED50 for this effect is typically 0.015-0.13 ug/ml in the presence of 3 ng/ml rhLeptin.

Molecular Weight
This protein is fused with Fc fragment of human IgG1 at the C-terminus and has a calculated MW of 121 kDa expressed. The predicted N-terminus is Phe22. Protein migrates as 150-165 kDa in reduced SDS-PAGE resulting from glycosylation.

Background Information
Leptin receptor (LEPR), also known as LEP-R, cluster of differentiation 295 (CD295), OB-R and B219, is a single-transmembrane-domain receptor of the gp130 family of cytokine receptors. Leptin receptor exists as homodimer and binds Leptin with high affinity, thus mediates the biological function of the adipocyte-specific hormone Leptin. LEPR is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Mutations in this protein have been associated with obesity and pituitary dysfunction. Interaction of leptin and leptin receptor is crucial for body weight and bone mass regulation in mammals through hypothalamic effects on satiety and energy expenditure. Meanwhile, research data supports a leptin receptor activation model based on ligand-induced conformational changes.

Properties
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
