Epidermal Growth Factor Rat
 
Catalogue Number CYT-556
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 purified from submandibular gland is a single, glycosylated, polypeptide chain having a molecular mass of 6.15 kDa.
The EGF is purified by proprietary chromatographic techniques.
Source Adult Male Rat Submandibular Glands.
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation The protein was lyophilized from a concentrated (1mg/ml) solution containing 0.01M sodium acetate buffer.
Solubility It is recommended to reconstitute the lyophilized Epidermal Growth Factor in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability Lyophilized Epidermal Growth Factor Recombinant 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.
Purity Greater than 99.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
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.
