Human FGF-2

Human FGF-2

FGF-2 stands for fibroblast growth factor 2, also termed fibroblast growth factor basic (FGF-b) or basic FGF. Human FGF-2 is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.


Human FGF-2 can be used for a variety of applications, including:
  • Stimulation of proliferation and differentiation of several cell types, such as mesenchymal stromal cells, neural cells, and endothelial cells.
  • Long-term maintenance and propagation of undifferentiated embryonic and induced pluripotent stem cells.
  • Differentiation of neural cells starting from embryonic and induced pluripotent stem cell cultures.

Alternative names

basic FGF, HBGF-2

Background information

Fibroblast growth factor 2 (FGF-2), also termed fibroblast growth factor basic (FGF-b) or basic FGF (bFGF), belongs to the family of heparin-binding growth factors. It functions as a wide-spectrum mitogenic, angiogenic, and neurotrophic factor and stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal, and endothelial cells. FGF-2 has been implicated in a multitude of physiological and pathological processes, including limb development, angiogenesis, wound healing, and tumor growth.

Quality description

cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
cytokines offer the convenience of high and well-defined biological activities and allow exact unit dosing for demanding applications. The biological activity is determined after lyophilization and reconstitution, and normalized to WHO/NIBSC standards whenever available. In general, endotoxin levels are <0.01 ng/μg (<0.1 EU/μg), and purities are >97%. Lot-specific certificates of analysis are available on request (
