Artificial base mismatches-mediated PCR (ABM-PCR) for detecting clinically relevant single-base mutations.

Objectives: Detecting point mutations with high sensitivity and specificity can be technically very challenging, but it is crucial for early diagnosis and effective drug treatment of cancers. To enable ultrasensitive and ultraspecific detection of single-base mutations in simple and economical ways, we have developed an artificial base mismatches-mediated PCR (ABM-PCR) detection approach.

Methods: ABM-PCR was applied to quantitative PCR (qPCR) and droplet digital PCR (ddPCR) detection platforms.
