Our bioactive FGF-2 (FGF-basic) Human, Plant Recombinant Protein (146 aa), also known as truncated Fibroblast Growth Factor 2, is a single, non-glycosylated, polypeptide chain that contains 146 amino acids and has a ~17 kDa molecular mass. The FGF-2 was expressed in rice plant (Oryza sativa) and purified by proprietary chromatographic techniques.


FGF-basic, a member of the fibroblast growth factor (FGF) family, is a non-glycosylated, heparin-binding growth factor and signaling protein encoded by the FGF2 gene. It binds to and exerts effects via specific fibroblast growth factor receptor (FGFR) proteins. Like other FGF family members, FGF-basic possesses broad mitogenic and cell survival activities, and is involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion.

Additionally, FGF-basic is a critical component of human embryonic stem cell (hESCs) culture medium; the growth factor is necessary for the cells to remain in an undifferentiated state. As a result, FGF-basic has been used to develop chemically-defined, serum-free and feeder-free hESCs culture mediums.

Other Names

Truncated Fibroblast Growth Factor-2, FGF2, FGF-2, FGF basic, FGF-b, Basic fibroblast growth factor, bFGF, Heparin-binding growth factor 2, HBGF-2.


Rice plant (Oryza sativa)


Sterile filtered white lyophilized (freeze-dried) powder. The protein was lyophilized from a concentrated solution without any additives.


Greater than 95.0% as determined by SDS-PAGE analysis.

Biological Activity

The ED50, as calculated by the dose-dependent proliferation of Balb/c 3T3 cells expressing FGF receptors is <1 ng/ml, corresponding to a specific activity of >1 x106 Units/mg.


It is recommended to reconstitute the lyophilized FGF-basic in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.


At ambient temperature. Upon receipt, store the product at the temperature recommended below.


Lyophilized FGF-basic, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution, FGF-basic should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
