(A) Mutant TP53 juice concentrations (mean mutation score) (y-axis) from subjects with pancreatic cancer and high-grade precursor lesions (x-axis) (*P = .0191). (B) TP53 mutation detected in a pancreatic juice sample from a subject with PanIN-3 (case 4, Table 3). Shifted melt curves, difference curves, and sequencing of digital HRM PCRs (arrows indicate mutations).

4. Supplementary Figure 1
Representative examples of shifted melting curves, difference curves, and Sanger sequencing. Identical TP53 mutations detected in both primary cancer tissue and juice samples by digital HRM and sequencing samples. (A) Exon 5; homozygous substitution, (B) exon 6; heterozygous substitution, (C) exon 7; deletion. Arrows indicate detected TP53 mutations. WT, wild-type control.

5. Supplementary Figure 2
Results of stepwise dilution test in (A) exon 7 and (B) exon 8. Shifted melting curves and difference curves with distinct differences from wild-type controls were shown in all 0.1% to 10% dilution levels. (C) Scatter-plot graph of actual and estimated number of positive wells. The R2 value was 0.985, indicating high accuracy of the HRM and dilution series.
