Featured product from Qkine
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) and carrier-protein free (CF)
- With no His-tag
