Cat#:RP-3232H;Product Name:Recombinant Human FGF4 Protein;Synonym:HBGF4, FGF-4, FGF4, KFGF, HSTF1.;Description:FGF4 Protein produced in E.coli is a single, non-glycosylated, polypeptide chain containing 182 amino acids and having a molecular mass of 19.8kDa. The FGF4 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:GRGGAAAPTA PNGTLEAELE RRWESLVALS LARLPVAAQP KEAAVQSGAG DYLLGIKRLR RLYCNVGIGF HLQALPDGRI GGAHADTRDS LLELSPVERG VVSIFGVASR FFVAMSSKGK LYGSPFFTDE CTFKEILLPN NYNAYESYKY PGMFIALSKN GKTKKGNRVS PTMKVTHFLP RL.;Purity:Greater than 95.0% as determined by SDS-PAGE.;Bioactivity:The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors is <0.5ng/ml, corresponding to a specific activity of > 2,000,000units/mg.;Formulation:The FGF4 protein was lyophilized with 2xPBS, pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized FGF4 Human Recombinant sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized FGF4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF-4 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.;
