Qk027 FGF2 / bFGF (human) Qkine protein vial
recombinant human FGF-2 (bFGF) 154 aa protein (Qk027)£100.00£600.00

Human FGF-2 / bFGF 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-derived component free (ACDF) and carrier-protein free (CF).

recombinant FGF2-G3 145 aa protein (Qk052)
recombinant FGF2-G3 145 aa protein (Qk052)£120.00£3,000.00

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 protein (Qk053)
recombinant FGF2-G3 protein (Qk053)£120.00£3,000.00

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).

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 mouse FGF-2 (bFGF) protein (Qk042)£100.00£600.00

mouse FGF2 / bFGF protein is an important factor in the maintenance of mouse epiblast-derived stem cells (EpiSC). Mouse naïve pluripotency is maintained by LIF, BMP4, and Wnt signalling pathways. However, the primed state of pluripotency in mouse EpiSCs is more similar to hESC and hiPSC, being maintained by FGF2 and TGFβ/Activin/Nodal pathways.1,2
