DESCRIPTION: Epidermal Growth Factor (EGF) is a polypeptide growth factor which stimulates the proliferation of a wide range of epidermal and epithelial cells. Human EGF is a 6.2 kDa protein containing 53 amino acid residues.

SOURCE: E. coli 
PURITY: Greater than 95% by SDS-PAGE and HPLC analyses. Endotoxin level is less than 0.1 ng per µg (1EU/ug) of EGF.

ACTIVITY: Human EGF is fully biologically active when compared to standards. The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BALB/c 3T3 cells is < 0.1 ng/mL, corresponding to a specific activity of > 1 x 107 units/mg.

APPLICATIONS: For most in vitro applications, EGF exerts its biological activity in the concentration range of 0.5 to 25.0 ng/mL. Responding cells are (partial list): Epidermal mesothelial cells.

PRESENTATION: Lyophilized powder with no additives.

Size: 0.1mg,1mg,10mg,1g etc.

STORAGE: The lyophilized EGF, 2-8 Deg (in refrigerator) storage, stable within 36 months.
