Recombinant Human FGF-21 Protein
|Fibroblast Growth Factor 21||
Fibroblast Growth Factors (FGFs) are a 22 member family of proteins known to be involved in angiogenesis, wound healing and embryonic development. As a family, they bind to heparin and signal through four receptor tyrosine kinases called, FGFR1, 2, 3 and 4. FGF-21 is most closely related to FGF-19 and shows low binding to heparin and is highly diffusible. Recombinant human FGF-21 is a non-glycosylated protein.
The activity is determined by the dose-dependent proliferation of NIH 3T3 cells in the presence of 5 μg/mL FGF binding protein and is typically 0.12-0.6 μg/ml.

Sterile filtered white lyophilized (freeze-dried) powder.
Lyophilized from 10 mM NaP, pH 7.5 + 100 mM NaCl.
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions.
Lyophilized product is very stable at -20°C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended to add a carrier protein (0.1% HSA or BSA) for long term storage.
Protein Content determined by
UV spectroscopy at 280 nm. Quantitation on SDS-PAGE against a known standard.
Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug.
