Abstract: A: Analysis of dilution series of indicated mutant EGFR variants spiked into 60 ng (â‰^18,180 genome equivalents) of WT DNA. Each data point represents one preparative within 6 independent dilutions series prepared and analyzed by two operators on two different instruments on three non-consecutive days for a total of 18 samples per dilution point. An analysis algorithm was applied to transform the mutant EGFR sequencing reads into the absolute mutant copies detected. The box-and-whisker plots show the median (center line), 25th and 75th percentiles (box) with the connecting "whiskers" extending from the first quartile minus 1.5 of the interquartile range (IQR, the third quartile less the first quartile) and the third quartile plus 1.5 of the IQR. A positive Spearman's correlation close to 1 indicates a strong, positive relationship between the absolute mutant EGFR copies detected and the absolute mutant EGFR copies per input. B: Inter-run reproducibility of the EGFR exon 19 deletions, L858R and T790M enrichment PCR-NGS assays for the dilution series shown in panel A. The Coefficient of Variation Percent (CV%) was calculated as the ratio of the standard deviation to the mean of the absolute EGFR copies detected within each absolute copy per input level and is reported as a percentage.
