Recombinant human fibroblast growth factor 2 (FGF-2) protein (154 aa) is a highly bioactive, long–form of FGF-2/bFGF protein. FGF-2 protein is used to support the maintenance of human embryonic stem cells and proliferation and differentiation of induced pluripotent and mesenchymal stem cells. This 154 aa form of FGF-2 comprises the core structured region and N-terminal extension.

Highly pure and bioactive 17 kDa FGF-2 / bFGF protein, animal origin-free (AOF) and carrier protein-free (CF).
