FGF-23 is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FGF-23 is most highly expressed in bone, from which it circulates through the blood to regulate vitamin D and phosphate metabolism in kidney.

Source:
Escherichia coli
Endotoxin Test:
<0.1 EU per 1 μg of the protein by the LAL method.
Activity:
Measure by its ability to induce proliferation in BaF3 cells transfected with human FGFRIIIc. The ED50 for this effect is <0.3 μg/mL.
Purity:
>98% as determined by SDS-PAGE. Ni-NTA chromatography
Formulation:
The protein was lyophilized from a solution containing 1X PBS, pH 8.0.
Reconstitution:
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 for at least 20 min to ensure sufficient re-dissolved.
Storage:
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.
Note:
Please use within one month after protein reconstitution.
