Fibroblast growth factor 8b (FGF-8b) is a member of the FGF family involved in the regulation of embryogenesis, cellular proliferation, differentiation, and migration.
FGF8b is commonly used for the differentiation of induced pluripotent stem cells into neural cell types and brain organoid cultures.
FGF8b is a spliced form of FGF8, a heparin-binding protein that targets mammary and non-mammary cells expressing the FGF receptors. A 22.5 kDa highly pure, bioactive recombinant protein produced in an animal origin-free expression system. This protein is carrier-free, tag-free and non-glycosylated to ensure a pure, homogenous protein with exceptional lot-to-lot consistency. Qk057 is suitable for enhanced reproducibility and physiologically relevant cultures.
