Human epidermal growth factor (EGF) protein is a potent EGF-family growth factor used in many human and mouse organoid and stem cell culture systems including intestinal and tumor organoid culture. EGF is also used in epithelial cell culture.

Qkine human EGF (Qk011) is a highly pure, animal origin-free, bioactive 6.3kDa recombinant protein, making it ideal for use in chemically defined induced pluripotent stem cell (iPSC), embryonic stem cell (ESC) and organoid culture media.
