Product Name: Fibroblast Growth Factor-4 Human Recombinant Synonyms: HBGF4, FGF-4, FGF4, KFGF, HSTF1. Description: FGF4 Human Recombinant 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. Uniprot Accesion Number: P08620 Amino Acid Sequence:GRGGAAAPTA PNGTLEAELE RRWESLVALS LARLPVAAQP KEAAVQSGAG DYLLGIKRLR RLYCNVGIGF HLQALPDGRI GGAHADTRDS LLELSPVERG VVSIFGVASR FFVAMSSKGK LYGSPFFTDE CTFKEILLPN NYNAYESYKY PGMFIALSKN GKTKKGNRVS PTMKVTHFLP RL. Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized FGF4 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution FGF-4 should be stored at 4C between 2-7 days and for future use below -18C.Please prevent freeze-thaw cycles. Formulation and Purity: The FGF4 protein was lyophilized with 2xPBS, pH 7.4. Greater than 95.0% as determined by SDS-PAGE. Application: Solubility: It is recommended to reconstitute the lyophilized FGF4 Human Recombinant sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: 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. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY.
