P01132

The biological activity is measured in a proliferation assay using BALB/MK cells.

The protein was lyophilized from a concentrated (1mg/ml) solution containing 0.01M sodium acetate buffer.

Sterile Filtered White lyophilized (freeze-dried) powder.

Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

It is recommended to reconstitute the lyophilized Epidermal Growth Factor in sterile 18MΩ-cm H₂O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Mouse Submaxillary Gland.

Lyophilized Epidermal Growth Factor Mouse although stable at room temperature for 3 weeks, should be stored desiccated below
-18^oC. Upon reconstitution EGF should be stored at 4^oC between 2-7 days and for future use below -18^oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
