Introduction
Pro-Epidermal Growth Factor Isoform 1 or EGF, is a globular peptide (77aa residues) which includes three intra molecular disulfide bonds. This protein acts as a growth factor that mediates the growth and proliferation of different epithelial & epidermal cells. Among other processes that EGF is part of are inhibition of gastric secretion and wound healing. EGF is a ligand for class I tyrosine kinase receptor (c-erbB).
Description
EGF Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 77 amino acids (977-1029 a.a) and having a molecular mass of 8.6kDa.EGF is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
