Introduction | HB-EGF is an EGF related growth factor which signals via the EGF receptor, and stimulates the proliferation of SMC (smooth muscle cells), fibroblasts, epithelial cells and keratinocytes. HB-EGF is expressed in various cell types and tissues, including vascular endothelial cells and SMC, macrophages, skeletal muscle, keratinocytes and particular tumor cells. HB-EGF’s ability to explicitly bind heparin and heparin sulfate proteoglycans is dissimilar from other EGF-like molecules, and might be related to the enhanced mitogenic activity, relative to EGF, that HB-EGF exerts on smooth muscle cells. |
Description | HB-EGF His Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 109 amino acids (63-148) and having a molecular mass of 12.1kDa.
HB-EGF His is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. |
