The pyrogram of EGFR exon21 mutation and software analysis result. Panel A is a pyrogram of EGFR L858R mutation. The small peak at the dispensation position 8 (A peak) is seen in all cases with similar peak height regardless of different tumor loads, therefore it is considered as non-specific noise. Panel B is the software data analysis of Panel A, indicating which peak or which portion of a peak is from either wildtype or mutant gene.
