Background
Fibroblast growth factor 21 (FGF21) is a peptide hormone that is synthesized by several organs and regulates energy homeostasis. Excitement surrounding this relatively recently identified hormone is based on the documented metabolic beneficial effects of FGF21, which include weight loss and improved glycemia.
Description
Recombinant Human FGF21 Protein is expressed from Expi293 with mFc (IgG1) tag and Avi tag at the N-terminal. It contains His29-Ser209.
Target
FGF21
Species
Human
Gene/Protein ID
Q9NSA1-1
Exact Sequence
His29-Ser209
Molecular Weight
The protein has a predicted MW of 46.9 kDa. Due to glycosylation, the protein migrates to 52-60 kDa based on the Tris-Bis PAGE result.
Activity
Immobilized Human FGF21 at 2ug/ml (100ul/Well) on the plate. Dose response curve for Human Beta Klotho, His Tag with the EC50 of 1.48ug/ml determined by ELISA (QC Test). The affinity constant of 0.54nM as determined in SPR assay (Biacore T200). See testing image for detail.
Tag
N-mFc-Avi
Express System
Expi293
Purity
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization.
Stability and Storage

Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

Shipping
Shipped at ambient temperature.
Reconstitution

Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
