General description
Fibroblast Growth Factor-basic (FGF-b) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. FGF-b also exerts a potent angiogenic activity in vivo. Human FGF-b is a 17.2 kDa protein containing 155 amino acid residues.
Fibroblast Growth Factor-basic (bFGF) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. bFGF also exerts a potent angiogenic activity in vivo. Human bFGF is a 17.2 kDa protein containing 155 amino acid residues. Xu, et al. demonstrated that bFGF synergizes with the BMP antagonist noggin to sustain undifferentiated proliferation of human embryonic stem (hES) cells under feeder-free conditions. GF003-AF was developed without animal-based ingredients and can be used for the culture of hES cells in a feeder-free, animal-free culture system.
expressed in E. coli
Application
For most in vitro applications, bFGF exerts its biological activity in the concentration range of 0.1 to 10.0 ng/mL. Responding cells are (partial list): Endothelial, mesenchymal cells. Human ES cells require concentrations in the range of 4 to 100 ng/mL, depending on the method of culture.
Optimal working dilutions must be determined by end user.

Analysis Note
Chemicon′s Human FGF-b is fully biologically active when compared to standards. The ED50 was determined by the dose-dependent stimulation of thymidine uptake by NIH3T3 cells expressing FGF receptors.
