Species of Origin
His Tag (C-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 20.35 kDa.
The protein migrates as 25 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to induce proliferation in BaF3 cells transfected with human FGFRIIIc. The ED₅₀ for this effect is <0.4 μg/mL.
<0.1 EU per 1 μg of the protein by the LAL method.
Fibroblast Growth Factors-21 (FGF-21) is a 22.3 kDa member of the fibroblast Growth Factors with 209 amino acid residues. FGF-21 is expressed from liver and cardiomyocytes. FGF-21 is a key protein that regulates important metabolic pathways, and modulates cellular function, metabolism, and senescence. It can stimulate glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1 /GLUT1 expression.
Fibroblast Growth Factors 21
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.
