Human FGF-2 Recombinant Protein

Human Recombinant Basic Fibroblast Growth Factor is a member of the fibroblast growth factor (FGF) family. FGF (often referred to as bFGF or FGF-2) family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion.

Human Fibroblast Growth Factor-2 (FGF-2) is a recombinant protein produced in  the endosperm of barley grain (Hordeum vulgare). It is a single, non-glycosylated, polypeptide chain containing 146 amino acids, plus a 10 amino acid tag at the N-terminus resulting in a 17.8 kDa protein. FGF-2 is purified by proprietary chromatographic techniques.


Pluripotent human stem cell (iPSC & ESC) culturing: Human FGF-2 also promotes long-term maintenance and propagation of undifferentiated human embryonic and induced pluripotent stem cells.

Culturing of neural stem cells-human, rat & mouse: FGF-2 is a necessary mitogen for the proliferation of neural stem cells and their maintenance of multipotency.


Activity is measured using a cell proliferation assay with NIH-3T3 cells. Activity is <0.2 ng/mL.

Purity and Identity

> 95%, by SDS-PAGE analysis with Coomassie blue staining. Identity is confirmed by Western blot analysis using protein specific antibody, ab10420 from Abcam.
