| Introduction | FGF-basic is a member of the fibroblast growth factor （FGF） family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors. |
| Description | Fibroblast Growth Factor-2 Human Recombinant （FGF-2） produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 147 amino acids and having a molecular mass of 16539 Dalton.
The FGF2 is purified by proprietary chromatographic techniques. |
| Source | Escherichia Coli. |
| Physical Appearance | Sterile Filtered White lyophilized （freeze-dried） powder. |
| Formulation | The bFGF was lyophilized from a concentrated （1mg/ml） sterile solution containing 10mM sodium phosphate buffer pH=8. |
| Solubility | It is recommended to reconstitute the lyophilized FGF-B in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized basic-FGF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGFb should be stored at 4°C between 2-7 days and for future use 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. |
| Purity | Greater than 95.0% as determined by（a） Analysis by RP-HPLC.
（b） Analysis by SDS-PAGE. |

| Biological Activity | The ED50, measured in a mitogenic assay using quiescent NR6R-3T3 fibroblasts was found to be less then 0.1 ng/ml, corresponding to a specific activity of 3 x 106 Units/mg. |
