Catalog #E3374-07
Biological Activity The optimal EGF concentration in cell culture is 0.125ng/ml depending on cell type.
Biological Activity 5ng/ml of this lot supports a 2.5- fold increase in cell number in a 5-day assay using human foreskin broblasts. Previously, 5ng/ml EGF supported a 2.2-fold increase in cell number in a 5-day assay using normal rat kidney broblasts (NRK-49F).
Storage and Stability May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20°C or colder. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
