Figure 3 Digital droplet polymerase chain reaction cell-free DNA (cfDNA) KRAS 12/13 analysis. Distribution of droplets is visualized using a heat map. Droplet threshold are shown as pink lines. Signal detected in the channel represents DNA positive for a KRAS 12/13 mutation. Signal detected in HEX channel represents DNA positive for KRAS wild-type (WT) amplification in which cfDNA mutants were nondetectable. (A) Sample positive for a mutation in codon 12/13 in the KRAS gene. Distribution of negative droplets (NEG), droplets positive for mutation in KRAS codon 12/13 (KRAS 12/13+), and droplets positive for KRAS WT. (B) Sample negative for mutation in codons 12/13 of the KRAS gene, but amplifies KRAS WT. (C) Sample without DNA showing no positive droplets in neither the FAM channel nor the HEX channel.
