Epidermal Growth Factor (EGF) is a growth factor that stimulates the proliferation, differentiation, and survival of epithelial and epidermal cells. EGF contains three intramolecular disulfide bonds and binds in high affinity to the epidermal growth factor receptor (EGFR). EGF is overexpressed in multiple tumor cell lines and promotes resistance to chemotherapy and radiation treatments.

Activity Assay

Rat EGF is fully biologically active when compared to standard. The activity is determined by the dose-dependent proliferation of BALB/c 3T3 cells proliferation and it is typically less than 1 ng/ml. This corresponds to an expected specific activity of 1.0 x 106 units/mg.
