Recombinant Human FGF21, His-tagged

Cat. No.: FGF21-104H
Product Overview: Recombinant Human Fibroblast Growth Factor-21 produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 181 amino acids and an N-terminal Methionin (bold), having a molecular weight of 19.7 kDa (calculated). The amino acid sequence of the recombinant human FGF21 is 100% homologous to the amino acid sequence of the human FGF21 without signal sequence and contains 14 a. His-tag at N-terminal.
Description: FGF-21 is a unique member of FGF super family that is reported to be primarily produced by the liver. FGF-21 has recently been shown to have beneficial effects on a variety of metabolic parameters, including glucose and lipid metabolism and insulin sensitivity in animal models and is thought to exert potent antidiabetic and lipid-lowering agent of obesity and type 2 diabetes mellitus. FGF-21 activity depends on membrane protein beta Klotho that physically complexes with various FGF receptors, thus conferring them the ability to bind FGF-21 and activate downstream signaling pathways.
Source: Escherichia Coli.
