Product Name: Fibroblast Growth Factor-Basic Human Recombinant Synonyms: Prostatropin, HBGH-2, HBGF-2, FGF-2, FGF-b. Description: Fibroblast Growth Factor-2 Human Recombinant (FGF-2) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 154 amino acids and having a molecular mass of 17.2kDa.The FGF-b is purified by proprietary chromatographic techniques. Uniprot Accesion Number: P09038 Amino Acid Sequence:AAGSITTLPA LPEDGGSGAF PPGHFKDPKR LYCKNGGFFL RIHPDGRVDG VREKSDPHIK LQLQAEERGV VSIKGVCANR YLAMKEDGRL LASKCVTDEC FFFERLESNN YNTYRSRKYT SWYVALKRTG QYKLGSKTGP GQKAILFLPM SAKS. Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized Fibroblast Growth Factor-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution FGF-b should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. Formulation and Purity: The protein was lyophilized from a concentrated (1mg/ml) solution in PBS, pH 7.4. Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. Application: Solubility: It is recommended to reconstitute the lyophilized Fibroblast Growth Factor Basic in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: 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 2, 000, 000 Units/mg. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
