Description
EREG Human Recombinant produced in HEK293 cells is a single, glycosylated polypeptide chain (63-108a.a) containing 289 amino acids and having a molecular mass of 32.6 kDa. EREG is fused to a 239 amino acid hIgG-His-Tag at C-terminus & purified by proprietary chromatographic techniques.
Synonyms
EPR, Epiregulin, Ep, ER, Proepiregulin, EREG.
Introduction
Epiregulin is part of the EGF family. Epiregulin functions as a ligand of EGFR, as well as a ligand of most members of the ERBB (v-erb-b2 oncogene homolog) family of tyrosine-kinase receptors.Epiregulin is expressed mostly in the placenta and peripheral blood leukocytes and in specific carcinomas of the bladder, lung, kidney and colon. Epiregulin stimulates the proliferation of keratinocytes, hepatocytes, fibroblasts and vascular smooth muscle cells. Epiregulin inhibits the growth of several tumor-derived epithelial cell lines. Human Epiregulin is initially synthesized as a glycosylated 19.0 kDa transmembrane precursor protein, which is processed by proteolytic cleavage to produce a 6.0 kDa mature secreted sequence.
Biological Activity
Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50 range ≤ 1ug/ml.
Physical Appearance
Sterile filtered colorless solution.
Formulation
EREG protein (0.25mg/ml) contains 10% glycerol and Phosphate-Buffered Saline (pH 7.4).
