- Human FGF2 /bFGF protein (145 aa) is our gold-standard and recommended FGF2 / bFGF protein for induced pluripotent stem cell (iPSC) and embryonic stem cells (ESC) maintenance, and induced pluripotent and mesenchymal stem cells proliferation and differentiation.High purity and bioactivity 17 kDa FGF2 / bFGF protein, animal-derived component free (ACDF) and carrier-protein free (CF) comprising the core structured region (145 amino acids) sufficient for full biological activity.
- Recombinant human FGF2 protein (154 aa) is a highly bioactive, long–form of human fibroblast growth factor 2 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.High purity and bioactivity 17 kDa FGF-2 / bFGF protein, animal-free (AOF) and carrier-protein free (CF).
- FGF2-G3 (145 aa) protein is a thermostable engineered form of FGF-2 (bFGF). Qk052 comprises the 145 aa form of FGF-2 (Qk025) with the nine amino acid substitutions developed by Dvorak et al. 2018. This increases the functional half-life of the protein from <10 h (wild-type) to >7 days (FGF2-G3 145 aa).FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. This new 145 aa thermostable FGF-2 protein allows direct comparison of efficacy in systems using FGF-2 145 aa (Qk025) for chemically defined stem cell and organoid culture media, and cultured meat media development.High purity 16 kDa bioactive FGF2-G3 145 aa protein. Animal-free (AOF), carrier protein-free and with no His-tag.
- Recombinant FGF2-G3 (FGF2-STAB®) protein is a thermostable engineered form of FGF-2 (bFGF). Qk053 is the 154 aa mature domain of FGF-2 (Qk027) with nine amino acid substitutions to enhance stability without impacting bioactivity developed by Dvorak et al. 2018. This increases the functional half-life of the protein from <10 h (wild-type) to >7 days (FGF2-G3).Recombinant FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. FGF2-G3 also has applications in chemically defined stem cell and organoid culture media, and cultured meat media development.High purity 17 kDa bioactive FGF2-G3 protein. Animal-free (AOF), carrier protein-free and with no His-tag.
- Recombinant bovine/porcine FGF2 protein 145 aa (bFGF/basic FGF) for the development of species-specific bovine (cow) and porcine (pig) cellular agriculture protocols and veterinary research applications. Used in comparative cell culture media optimization studies alongside Qk056, the 154aa form of porcine/bovine FGF-2.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 protein, animal origin-free (AOF) and carrier-protein free (CF).
- 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).
