• Host: E Coli
• Purity/Purification: Greater than 98.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
• Form/Format: Rat EGF was lyophilized from a 0.2 um filtered concentrated (1.0mg/ml) solution in PBS, pH 7.4.; Sterile Filtered White lyophilized (freeze-dried) powder.
• Sequence: NSNTGCPPSY DGYCLNGGVC MYVESVDRYV CNCVIGYIGE RCQHRDLRWW KLR
• Sequence Length: 1133

• Solubility: It is recommended to reconstitute the lyophilized Rat EGF in sterile water not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
• 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 > 10,000,000 units/mg.
• Preparation and Storage: Lyophilized Rat EGF although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution Rat EGF should be stored at 4 degree C between 2-7 days and for future use below -18 degree C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.

Related Product Information for rEGF active protein

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.

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.

binds the epidermal growth factor receptor; may play a role in MAP kinase mediated signaling pathways [RGD, Feb 2006]

Uniprot Description

EGF: 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. Defects in EGF are the cause of hypomagnesemia type 4 (HOMG4); also known as renal hypomagnesemia normocalciuric. HOMG4 is a disorder characterized by massive renal hypomagnesemia and normal levels of serum calcium and calcium excretion. Clinical features include seizures, mild-to mederate psychomotor retardation, and brisk tendon reflexes. 2 isoforms of the human protein are produced by alternative splicing.
