EGFR and mAb806 epitope expression were determined in MSTO-211H, NCIH-28, NCIH-2052 and NCIH-2452 mesothelioma cell lines in a series of binding assays by immunohistochemistry, Fluorescence-activated cell sorting (FACS) and Western blot analysis (Figure 1). This evidence concerns the gene EGFR and mesothelioma.
