G12D KRAS mutation detection in plasma and genomic DNA by QX200™ Droplet Digital™ PCR. b. Frequency of mutant KRAS detection in plasma in PDAC. c. Correlation of cfDNA concentration and mutant KRAS detection. *DNA concentration was estimated by the number of copies of the RNaseP gene in 20 μl of cfDNA in plasma. d.
