Species of Origin
His-SUMO Tag (N-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 29.35 kDa.
The protein migrates as 36 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to induce 3T3 cells proliferation. The ED₅₀ for this effect is <2 ng/mL.
<0.1 EU per 1 μg of the protein by the LAL method.
Fibroblast Growth Factors-22 (FGF-22) is a 22.3 kDa member of the fibroblast Growth Factors with 209 amino acid residues. FGF-22 is expressed from brain, skin, horizontal cells, bipolar cells, rod photoreceptor cells, muller glia cells. Involving fasting response, glucose homeostasis, lipolysis, lipogenesis and hair development.
Fibroblast Growth Factors 22
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.
