EGFR gene amplification, mutation and re-arrangement are frequently observed in primary glioblastoma multiforme (GBM). The most common EGFR variant in GBM, EGFRvIII, is characterized by a deletion of 267 amino acids in the extracellular domain, leading to a receptor that is unable to bind ligand yet is constitutively active. EGFRvIII enhances the tumorigenic potential of GBM by activating and sustaining mitogenic, anti-apoptotic, and pro-invasive signaling pathways.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eKinase\u003c\/span\u003e\n\u003cp\u003eRecombinant hEGFRvIII-CHO K1 cell line stably expressing full-length human EGFRvIII receptor (accession number NP_001333870).
