  • Patent number: 11193167
    Abstract: Multiplex pyrophosphorolysis activated polymerization uses multiple pairs of blocked primers to amplify multiple potential templates in a single reaction, including those almost-sequence-identical templates located in one locus. To identify and differentiate the multiple amplified products, individual molecules are sequenced in parallel. Thus multiplex PAP amplification is combined with parallel sequencing for ultrahigh-sensitive, ultrahigh-selective and ultrahigh-throughput detection of early cancer.
