Data

Background

Epidermal growth factor (EGF), also known as Urogastrone, is a growth factor that plays an important role in the regulation of cell growth, proliferation and differentiation (1). It is produced by many cell types, in blood and various body fluids, including milk, urine, saliva, seminal fluid, pancreatic juice, cerebrospinal fluid, and amniotic fluid (1). EGF acts by binding with high affinity to epidermal growth factor receptor (EGFR) on the cell surface, activating an extensive network of signal transduction pathways that include PI3K/AKT, RAS/ERK and JAK/STAT. It is also a mitogen for fibroblasts, epithelial and endothelial cells, and promotes colony formation of epiderma. EGF has been shown to regulate tumor cell invasion through MMP-2 activation in various tumor cell types (2). Additionally, EGF has been shown to inhibit gastric secretion, and to be involved in wound healing (3). Because of its key role in driving the proliferation of cells, EGFR is a target of several anti-cancer drugs currently in development.

Protein Details

Purity
>97% by SDS-PAGE and analyzed by silver stain.
Endotoxin Level
<0.1 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human EGF was determined by its ability to stimulate proliferation in an EGF-responsive mouse fibroblast cell line, Balb/3T3 (Rubin, J.S. et al., 1991, Proc. Natl. Acad. Sci. USA 88:415). The expected ED50 is typically 20 - 100 pg/ml.
