Description of Human FGF-basic, FGF-2

Recombinant human Fibroblast Growth Factor-basic (hFGF-b) is a 16.5 kDa protein containing 153 amino acid residues. Interestingly, hFGF-b contains no hydrophobic leader sequence previously thought 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. hFGF-b is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. It also exerts a potent angiogenic activity in vivo. 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. In general FGFs 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. One of the most potentially significant applications of FGF-b is related to its reported ability to induce angiogenesis.


Biological Activity

The ED50 of ≤ 2 ng/ml was determined by stimulation of cell proliferation in HUVEC (human umbilical vein endothelial cells) in direct Comparison with WHO standard #90/712. It corresponds to a specific activity of ≥ 5.0 x 105 IU/mg.



We recommend a quick spin followed by reconstitution in water to a concentration at least 0.05 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (0.1% HSA , order number: or, or BSA) and store in working aliquots at -20C to -80C for up to 12 months.



Lyophilized samples are stable until expiry date at -20C to -80C. FGF-basic can be stored in high-salt buffer (PBS, 1M NaCl) at 4C for 2-4 weeks. Please avoid repeated freeze-thaw cycles.
