FIGURE 1 Genomic DNA was isolated from paraffin-embedded tumor samples. EGFR gene exons 18, 19, 20, and 21 were each amplified by polymerase chain reactions, and the products were screened for mutations by denaturing high-performance liquid chromatography (A). An additional peak in the exon 21 amplicon was observed and direct sequencing revealed mutation p.Arg859Asp (B).
