General description

Product Source: HumanKine growth factors are expressed in a proprietary human 293 protein expression system and are manufactured without the use of any animal products and are considered Xeno-Free.
The HumanKine Thermostable bFGF is engineered with enchanced thermostability compared to the wild-type bFGF protein without modification of biological function.

Fibroblast Growth Factor-basic (bFGF) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. bFGF also exerts a potent angiogenic activity in vivo. Human bFGF is a 17.2 kDa protein containing 154 amino acid residues. bFGF synergizes with the BMP antagonist noggin to sustain undifferentiated proliferation of human embryonic stem (hES) cells under feeder-free conditions.

Application

Engineered bFGF growth factor with enchanced thermostability compared to the wild-type bFGF protein. Allows a less vigorous feeding schedule for human es/ips and neural stem cell culture.

Quality

Bioactivity assay: Determined by the dose-dependent stimulation of the proliferation of the 3T3 cell line. EC50 is typically ≤0.5 ng/mL.

Physical form

Lyophilized from a 0.2 μm filtered solution of 1X PBS.

Storage and Stability

Store at -20°C for up to 4 months from date of receipt. Further dilutions should be made into appropriate buffer or medium to which protein has been added.
