Fibroblast Growth Factor 20, Human (FGF20) Recombinant

The FGF family plays important roles in morphogenesis, cellular differentiation, angiogenesis, tissue remodeling, in?ammation and oncogenesis. Fibroblast Growth Factor-20 (FGF-20) is a newly discovered neurotrophic factor belonging to the FGF family. FGF-20 is most similar to FGF-9 and FGF-16. Recombinant Human FGF-20 is a 23.2kDa protein containing 209 amino acid residues.\n\nReconstitution: Reconstitute in sterile dH2O to a concentration of 0.1-1mg/ml. This solution can then be diluted into other aqueous buffers. \n\nBiological Activity: The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors is (same/less than)10ng/ml, corresponding to a speci?c activity of (same/more than)1 x 10e5 units/mg. \n\nStorage and Stability:\nLyophilized powder may be stored at 4 degrees C for short-term only. Reconstitute to nominal volume and store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.\n\nCountry of Origin: USA
