| Fibroblast growth factor 4 is a member of the FGF family, a group of 7 homologous polypeptides that act upon a variety of cells and produce biological actions that may include cell proliferation, migration and differentiation. FGF4, also known as oncogene products hst1 and KFGF, has strong transforming potential and is a potent angiogenic factor, being expressed in several highly vascularized tumors. | | | Catalog # | F4210-50A | | Source | Recombinant corresponding to 182aa from human Fibroblast Growth Factor 4 expressed in E. coli. | | Molecular Weight | ~19.7kD | | Endotoxin | 0.1ng/ug | | Biological Activity | ED50 0.5ng/ml ( 2x10e6 units/mg), determined by the dose dependent stimulation of thymidine uptake by BaF3 cells expressing FGF-receptors. FGF-4 is a heparin binding growth factor expressed by tumor cells and embryonic cells which has mitogenic activity with fibroblasts and endothelial cells. | | Applications | Suitable for use in Neutralization. Other applications not tested. | | Recommeded Dilutions | Optimal dilution to be determined by the researcher. | | Storage and Stability | Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C with a carrier protein. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | | Molecular Weight | 19.7kD | | Source | E. coli | | Purity | ~95% (SDS-PAGE). Purified by sequential chromatography. | | Concentration | Not determined | | Form | Supplied as a lyophilized powder from 10mM sodium phosphate, pH 7.4, 100mM sodium chloride, 1.25mg BSA. Reconstitute with sterile ddH2O to 0.1-1mg/ml. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
