Product Description

GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!

Recombinant Human Epiregulin

EREG is a member of the epidermal growth factor (EGF) family and is expressed mainly in the placenta and peripheral blood leukocytes, as well as in certain carcinomas of the bladder, lung, kidney, and colon. EREG stimulates the proliferation of keratinocytes, hepatocytes, fibroblasts and vascular smooth muscle cells. Additionally, it inhibits the growth of several tumor-derived epithelial cell lines. EREG is synthesized as a transmembrane protein and the ectodomain is cleaved by a protease to release the mature protein. The mature protein can bind to EGFR, as well as most members of the ERBB family of RTKs.
