Mouse recombinant FGF-21 (Fibroblast growth factor-21) protein, AF

About this product

Fibroblast Growth Factors 21 (FGF-21) is a 23 kDa protein with 210 amino acid residues. Belongs to FGF superfamily, FGF-21 is related to glucose and lipid metabolism. Peroxisome proliferator-activated receptor gamma (PPARg) and peroxisome proliferator-activated receptor alpha (PPARa) regulate FGF-21 expression.

Applications

Cell Culture

Purification

>98% as determined by SDS-PAGE.

Endotoxin

<0.1 EU per 1 μg of the protein by the LAL method.

Bioactivity

Measure by its ability to induce proliferation in NIH‐3T3 mouse embryonic fibroblast cells in the presence of mouse Klotho beta and heparin. The ED50 for this effect is < 2 μg/mL.

Form

The protein was lyophilized from a 0.2 μm filtered solution containing 1X PBS, pH 8.0. If you have any concerns or special requirements, please confirm with us.

Reconstitution

Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.

Molecular Weight

The protein has a calculated MW of 20.76 kDa. The protein migrates as 25-35 kDa under reducing condition (SDS-PAGE analysis) .

Storage Conditions

Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
