FGF-2, also known as a basic fibroblast growth factor (bFGF) and FGF-β, is a growth factor and signaling protein encoded by the FGF-2 gene. FGF-2 has been shown in preliminary animal studies to protect the heart from injury associated with a heart attack, reducing tissue death and promoting improved function after reperfusion. FGF-2 are also involved in a variety of biological processes, including embryonic development, morphogenesis, tissue repair, tumor growth, and invasion. Additionally, FGF-2 is frequently used for a critical component of cell culture medium, e.g., human embryonic stem cell culture medium, serum-free culture systems.

<0.1 EU per 1 μg of the protein by the LAL method.
Measure by its ability to induce 3T3 cells proliferation. The ED50 for this effect is <1 ng/mL.
The specific activity of recombinant human FGF-2 is approximately >5 x 105 IU/mg.
>98% as determined by SDS-PAGE. Purified by Ni-NTA chromatography.
The protein was lyophilized from a solution containing 0.01% sarkosyl in 1X PBS, pH 8.0.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Lyophilized protein should be stored at -20°C. This product is stable for one year upon receipt, when handled and stored as instructed. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C. Avoid repeated freeze/thaw cycles.
Please use within one month after protein reconstitution.
