Datasheet Extract
| Background | The FGF family is composed of at least 22 polypeptides that show a variety of biological activities towards cells of mesenchymal, neuronal and epithelial origin. All members are heparin-binding growth factors (HBGF). Until the structure of basic fibroblast growth factor (bFGF/FGF-2) was determined, a number of synonyms was used to describe this growth factor. As is often the case, the nomenclature reflected the observed activities reported by individual groups. Basic FGF has been reported as leukemia growth factor, macrophage growth factor, endothelial growth factor and tumor angiogenesis factor. The eventual isolation and characterization of bFGF was done from soluble brain extracts. bFGF was found to have a molecular mass of 16 kDa and to be 154 amino acids in length. Interestingly, bFGF contains no hydrophobic leader sequence previously thougth to be required for cell secretion. Basic FGF bears 55% homology to acidic FGF and also seems to exist in three forms: the 154 amino-acid form and two other truncated versions of 146 and 131 amino acids lacking the N-terminal 9 and 24 residues. Acidic and basic FGF compete for the binding to 125 kDa and 145 kDa receptor species. However, acidic FGF has a higher affinity for the 125 kDa species, while basic FGF has a higher affinity for the 145 kDa species. FGF receptor activation leads to the activation of MAP kinase and protein kinase C. FGF's induce the proliferative response in cells derived from mesoderm and neuroectoderm. It seems that basic FGF reduces the average doubling time by shortening the G1 phase of the cell cycle. Furthermore, it has been reported to induce the release of plasminogen activator by endothelial cells. Perhaps one of the most potentially significant applications of bFGF is related to its reported ability to induce angiogenesis.

| Format | State: Lyophilized, no stabilizers added Purity: > 95% by SDS-PAGE and visualised by silver stain BufferSystem: PBS Endotoxinlevel: < 0.1 ng per µg of FGF-basic Reconstitution: Restore in 50 mM acetic acid containing at least 0.1% human or bovine serum albumin to a concentration not lower than 10 µg/ml. |
| Description | Recombinant polypeptide Biological Activity: The activity was determined by stimulation of 3H-thymidine incorporation in Balb/c 3T3 cells. The ED50 for this effect is 0.4-1.0 ng/ml. Maximal effect for DNA synthesis was observed at 1.0-2.0 ng/ml rh basic FGF. Molecular weight: 16.5 kDa |
| Storage | Lyophilized samples are stable for six months at -20°C to -70°C. Avoid repeated freeze-thaw cycles.
Basic FGF can be stored in high-salt buffers (PBS, 1 M NaCl) at 4°C for 2-4 weeks. |
