Synonyms	Urogastrone, URG, EGF.
Introduction	Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-bound molecule which is proteolytically cleaved to generate the 53-amino acid peptide hormone that stimulates cells to divide. EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture.
Description	Epidermal Growth Factor Rat Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 53 amino acids and having a molecular mass of 6151 Dalton. The Rat EGF is purified by proprietary chromatographic techniques.
Source	Escherichia Coli.
Physical Appearance	Sterile Filtered White lyophilized （freeze-dried） powder.
Formulation	Rat EGF was lyophilized from a 0.2μm filtered concentrated （1.0mg/ml） solution in PBS, pH 7.4.
Solubility	It is recommended to reconstitute the lyophilized Rat EGF in sterile water not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability	Lyophilized Rat EGF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Rat 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.
Purity	Greater than 98.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE.
Amino Acid Sequence	NSNTGCPPSY DGYCLNGGVC MYVESVDRYV CNCVIGYIGE RCQHRDLRWW KLR.
Biological Activity	The ED50 as calculated by the dose-dependant proliferation of murine BALB/c 3T3 cells is less than 0.1ng/ml, corresponding to a specific activity of > 1 x 107 units/mg.
Usage	ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
