Technical Data
Epidermal Growth Factor, Murine (EGF)
Molecular Biology Storage: -20CShipping: RT
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 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20C or colder. Aliquots are stable for at least 6 months at -20C. 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.

Molecular Weight:
Source: Mouse
Purity: Single band on SDS-PAGE gel at 16kDa (1ug run under non-reducing conditions and Coomassie blue stained).
Form: 100ug/vial of lyophilized powder. Lyophilized from 157ul of 20mM ammonium acetate. Quantitated by spectrophotometry using the extinction coef cient for EGF [E (1%, 280nm)]= 30.9
