 Background 
 EGF (Epidermal Growth Factor) Chinese name of the epidermal growth factor, is an important class of growth factors. EGF is a molecule consisting of 53 amino acid peptide chain, the chain contains six cysteine ??molecules, cysteine ??molecules form stable disulfide bonds, so that the entire peptide chain into three parts of the active substances TransUnion . EGF's main role is to promote skin cell proliferation, differentiation, accelerate the repair of injured skin cells and accelerate metabolism, increase new cell proportion in the skin, it can play a delay skin cell aging, the role of the skin soft and smooth. Also inhibit gastric acid secretion and other special effects, the medicine has a very wide use.

 Solution proposed 
 Provide human epidermal growth factor (EGF) for the filter-sterilized product lyophilized white powder; the lyophilized powder containing 1mg/ml from the human epidermal growth factor (EGF) in 10mM phosphate buffer (pH 7.4) in the freeze-dried generated. We recommend additional sterile 18MΩ-cm water for the preparation of working stock solution to 100μg/ml, follow-up experiment based on the experimental requirements can be further diluted. 

 Preservation proposal 
 Human epidermal growth factor (EGF) lyophilized powder can be stored at room temperature for 3 weeks, or placed in -18 ℃ cryopreservation for long-term preservation. Re-dissolved in 4 ℃ refrigerator for at least 2-7 days; If you want to extend the storage time, the proposed packing (plus carrier protein such as 0.1% HSA or BSA) and placed in -18 ℃ cryopreservation. Avoid repeated freezing and thawing.
