Recombinant Epidermal Growth Factor (OsrEGF)

 

Human epidermal growth factor, also known as EGF, is a 6kD protein with 53 amino acid residues and three intramolecular disulfide bonds. By binding with high affinity to epidermal growth factor receptor (EGFR) on the cell surface, EGF results in a variety of biochemical changes within the cell, rising intracellular calcium levels, increasing glycolysis, protein synthesis and regulating the gene expression, including the gene for EGFR that ultimately lead to DNA synthesis and cell proliferation.

1.SDS-PAGE                                                             2. Bioactivity

                                              

Two different batches OsrEGF resolved with SDS-PAGE.                    Cell proliferation assay was using Balb/C 3T3 mouse

Both of these two batches purity are higher than 95%.                     embryonic fibroblast cells. The bioactivity of OsrEGF

                                                                                                        is more than 1 x 106 Units/mg.
