Accelerated cycling PCR: A novel tool for rapid, sensitive and specific detection of single-nucleotide mutation within 30 min

Rapid detection of single-nucleotide mutations (SNMs) has played a vital role for point-of-care testing. We herein first introduced accelerated thermal cycling into conventional allele-specific qPCR (AS-qPCR), named accelerated cycling PCR (AC-PCR) to achieve rapid and sensitive detection of SNM. It could simultaneously detect 10 copies of H. pylori DNA and identify its clarithromycin-resistance genotype within 30 min, and showed 100-fold enhanced specificity than AS-qPCR. Therefore, AC-PCR shows great potential in clinical diagnosis for drug resistance mutation or genotyping analysis.
