Abstract
Quality check of DBS assays with artificially methylated standard DNAs. DNA standards of 0%, 25%, 50%, 75% and 100% methylation were sequenced with the PSMB5, PSMC2, PSMC5, PSMC6, PSMD1 and PSMD5 DBS assays to confirm assay sensitivity. Results for all investigated DBS amplicons correlated well with the expected curves (P < 0.001) (A). The sequencing depths of the PSMD5 DBS assay was 10-3 (B).
