Cat#:RP-3214H;Product Name:Recombinant Human FGF2 Protein, sf9;Synonym:Prostatropin, HBGH-2, HBGF-2, FGF-2, FGF-b.;Description:Fibroblast Growth Factor-2 Protein (FGF-2) produced in Sf9 insect cells is a single, glycosylated, polypeptide chain containing 155 amino acids and having a molecular mass of 17353 Dalton. The FGF-basic is purified by proprietary chromatographic techniques.;Source:Baculovirus.;AA Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Ala-Gly-Ser-Ile.;Purity:Greater than 98.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The ED50, calculated by the dose-dependant proliferation of BAF3 cells expressing FGF receptors (measured by 3H-thymidine uptake) is <0.5 ng/ml, corresponding to a specific activity of 2MU/mg.;Formulation:The sterile protein solution (0.5mg/ml) contains 20mM Tris pH=7.9, 100mM KCl, 1mM DTT and 20% glycerol.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Storage:Fibroblast Growth Factor-basic although stable at 4°C for 3 weeks, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
