recombinant FGF2-G3 (145 aa) protein

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). The original 154 aa form of FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. This new form allows direct comparison of efficacy in systems using FGF2 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-tags.
