Figure 1From: Detection of EGFR mutations with mutation-specific antibodies in stage IV non-small-cell lung cancerIHC analysis of EGFR mutations in five human NSCLC cell lines. A549 and H460 showed negativity for both mutation-specific antibodies. EGFR E746-A750 deletion specific (6B6) antibody stained H1650 and PC9 harboring the exon 19 deletion, and EGFR L858R mutant-specific (43B2) antibody stained the H1975 cell line with exon 21 mutation.Back to article page
