Table 3 Comparison of EGFR status (wild type (WT) or mutant (M)) of exon 19 and exon 21 determined by big dye sequencing or by pyrosequencing on 58 NSCLC tissues

From: Pyrosequencing, a method approved to detect the two major EGFR mutations for anti EGFR therapy in NSCLC

Exon 19   big dye sequencing Exon 21   big dye sequencing
   WT M    WT M
pyrosequencing WT 47 / pyrosequencing WT 53 /
