Recombinant bovine/porcine FGF2 protein 154 aa (bFGF/basic FGF), this is the long form of FGF-2 used for the development of optimized serum-free culture media for species-specific bovine (cow) and porcine (pig) cultivated meat and veterinary research applications. Used in comparative media optimization studies with Qk040 porcine/bovine FGF-2 145 aa.FGF-2 is used extensively in the maintenance and proliferation of induced pluripotent (iPSC) and embryonic stem cells (ESC)1-3  and for enhancement of proliferation in primary cell culture.High purity 16 kDa FGF-2 / bFGF 154 aa protein, animal origin free (AOF) and carrier-protein free (CF).
