Optimized DNA sequence  encoding extracellular domain of human leptin receptor  including a C-terminal polyHis tag was expressed in HEK293 cells.

Molecular weight:

Recombinant LEPR is a monomer protein consisting of 829 amino acid residue subunits,  due to glycosylation migrates as an approximately 130kDa protein on SDS-PAGE.

>98%, as determined by SDS-PAGE and HPLC

Biological Activity:
Measured by its ability to bind recombinant human Leptin at a concentration range of 0.03-40 ug/ml .

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant LEPR  is supplied as lyophilized 0.2 μm filtered PBS solution,  pH7.2 .

Recombinant LEPR, as supplied, can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

Leptin receptor

Leptin exerts its activity through specific membrane receptor, the obesity or leptin receptor (LEP-R), which is assigned to class I cytokine receptor family. Six splice variants of LEP-R have been identified up to now; a long isoform, four short isoforms discriminated by the different lengths of intracellular domain and the secreted isoform, which modulates blood leptin . According to the current knowledge, leptin-signaling pathway is mainly transduced by janus kinases/signal transducers and activators of transcription, mitogen- activated protein kinase and phosphatidylinositol 3- Kinase (PI3K)-signaling pathways. PI3K/AKT pathway may be set off through the activation of receptor tyrosine kinases by certain growth and survival factors (including Ob), through the activation of non-receptor tyrosine kinases or through Ras- signaling pathway activation . Activated PI3K phosphorylates phosphatidylinositol-3, 4- biphosphate and phosphatidylinositol-3, 4, 5-triphosphate. Phosphatidylinositol-3, 4- biphosphate and phosphatidylinositol-3, 4, 5-triphosphate activate a downstream target of PI3K namely AKT kinase that subsequently activate other targets including glycogen synthase kinase 3, FoxO1 and p27kip1.
