Recombinant hEGFRvIII-CHO K1 cell line stably expressing full-length human EGFRvIII receptor (accession number NP_001333870). Surface expression of hEGFRvIII was confirmed by flow cytometry. Each stable clonal cell line was selected for different levels of hEGFRvIII [removed]High and Low) to mimic different stages of cancer target cells with various EGFRvIII expression levels.
Mycoplasma testing: The cell line has been screened to confirm the absence of Mycoplasma species.
Host Species: hamster
Supplied as 2 vials of frozen cells. 2 x 10^6 in 1 ml of 90% FBS, 10% DMSO
Background
Background The epidermal growth factor receptor (EGFR, ErbB-1, HER1) belongs to a family of receptor tyrosine kinases that includes three other closely-related members (HER2, HER3 and HER4). 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.
Application
Screen for inhibitors of EGFRvIII signaling for immuno-oncology research and drug discovery.
