Validation of SNV-associated VAFs by SP-ddPCR in clinical patient samples. Plots show raw data output for fluorescence amplitude. Standard, total copies of the target gene measured by standard primers; SSP, quantification of SNV copies by SuperSelective primers; NTC, non-template control well containing equivalent amounts of DNA but not the target sequence.
