Description

Our bioactive Epidermal Growth Factor (EGF) Human, E. coli Recombinant Protein is a single, non-glycosylated, polypeptide chain containing 53 amino acids and has a molecular mass of 6.2 kDa. The EGF is purified by proprietary chromatographic techniques.

Summary

EGF acts a potent mitogenic factor that plays an important role in the growth, proliferation and differentiation of numerous cell types. This protein acts by binding with high affinity to the cell surface receptor, epidermal growth factor receptor (EGFR). EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. Magnesiotropic hormone that stimulates magnesium reabsorption in the renal distal convoluted tubule via engagement of EGFR and activation of the magnesium channel TRPM6.

Formulation

Sterile filtered white lyophilized (freeze-dried) powder. The protein was lyophilized from a concentrated (1 mg/ml) solution containing PBS pH-7.4.

Purity

Greater than 98.0% as determined by HPLC and SDS-PAGE analysis.

Biological Activity

The ED50 as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 0.1 ng/ml, corresponding to a specific activity of >1.0x107 IU/mg.

Reconstitution

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

Shipping

At ambient temperature.  Upon receipt, store the product at the temperature recommended below.

Storage/Expiration

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