EGF Recombinant Protein

The ED50 was determined by a cell proliferation assay using balb/c 3T3 cells is = 0.1 ng/mL, corresponding to a specific activity of = 1 x107 units/mg.

The lyophilized EGF recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted EGF is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing EGF recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
