Featured scientific areas
Thermostable FGF2-G3
Thermostable FGF2-G3 is a hyperstable form of FGF-2 (bFGF), essential for maintaining pluripotency in stem cell media.
Neural stem cell culture
High-quality growth factors are essential for developing and maintaining robust, reproducible, and physiologically relevant neural cultures.
Cultivated meat
Growth factors are critical components of cell culture media and provide the most reliable solution for cultivated meat and cellular agriculture.
