Heat Stable Recombinant Human bFGF (also known as fibroblast growth factor-basic, FGF-basic, FGF-β, or FGF2) is a full-length protein (containing 155 amino acid residues) that has been engineered for greater stability in cell culture conditions. It sustains ≥80% activity at 37°C for at least 72 hours compared to native bFGF, which has a half-life of <8 hours at 37°C.

Sequence identity
Heat Stable Recombinant Human bFGF has comparable biological function compared to native bFGF. It has >90% sequence homology to native bFGF, leaving heparin and FGF receptor binding sites untouched.

Heat Stable Recombinant Human bFGF retains bioactivity without the use of artificially high concentrations. Minimal fluctuation in protein activity more closely mimics physiological conditions for cells. This is key for challenging applications such as culturing bFGF-dependent cells or 3D cell culture where medium changes can be tedious.

Easy to use
Heat Stable Recombinant Human bFGF is a direct replacement for your current human bFGF. Reconstitute lyophilized protein in sterile distilled water (refer to product data sheet for recommended concentration). The 5-µg size is ideal for single use in 500 mL of medium at 10 ng/mL working concentration.
