The library was delivered into the EGFR-mutated (L858R and T790M) NSCLC cell line NCI-H1975 (Cragg et al, 2007), which was chosen because of the significant cell surface expression of the tumor antigens erb-B2 receptor tyrosine kinase 2 (Her2), EGFR, and epithelial cell adhesion molecule (EpCAM) (Fig S1A), frequently targeted by biAbs in clinical trials (Runcie et al, 2018). This evidence concerns the gene EPCAM and non-small cell lung carcinoma.
