Fibroblast Growth Factor, basic (syn.; FGF-2; HBGF-2) is 55% homology to FGF acidic and prototypic member of the fibroblast growth factor family. Fibroblast growth factor 2, also known as basic fibroblast growth factor (bFGF) and FGF-β, is a growth factor and signaling protein encoded by the FGF2 gene. It binds to specific fibroblast growth factor receptor (FGFR) proteins, a family of closely related molecules, and through them has a wide range of mitotic and cell survival activities, exerting a variety of biological effects including cell proliferation, differentiation, survival and apoptosis.
It supports the maintenance of undifferentiated human pluripotent stem cells, stimulates human pluripotent stem cells to form neural rosettes, and improves proliferation of human mesenchymal stem cells and enhances chondrogenic differentiation. Also it supports the maintenance of undifferentiated human pluripotent stem cells, stimulates human pluripotent stem cells to form neural rosettes, and improves proliferation of human mesenchymal stem cells and enhances chondrogenic differentiation

(A) The biological activity of Human Recombinant St-bFGF was tested by its ability to promote the proliferation of BALB/c 3T3 cells. Cell proliferation was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the under example is 0.33 ng/mL.
(B) Human Recombinant St-bFGF was resolved with SDS-PAGE under and visualized by Coomassie Blue staining. Human Recombinant St-bFGF has a predicted molecular mass of 16.4 kDa.
