Amphiregulin is a key EGF receptor ligand that drives autocrine and paracrine signaling in tumor proliferation, making it a critical target in cancer biology research. This tag-free recombinant human AREG (residues 101–198) encompasses the mature EGF-like domain responsible for EGFR binding, and its confirmed ED50 of 5–10 ng/mL in Balb/c 3T3 proliferation assays demonstrates robust receptor-binding potency suitable for cell proliferation and survival studies, EGFR-ligand competition assays by ELISA or SPR, and in vivo tumor biology models. The E. coli expression system yields a non-glycosylated protein that provides a defined, homogeneous preparation — an advantage when glycosylation variability could confound receptor-binding quantitation or use as an ELISA standard for antibody characterization. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typically required for sensitive cell-based assays and wound healing migration studies.
