  • Patent number: 11268140
    Abstract: Minimal-copy-ratio of templates is a problem in detecting early stage cancer where minimal copies of somatic cancer-specific mutations are targeted in the presence of large copies of wildtype genome DNA, commonly a 1/10,000 or even less minimal-copy-ratio between the mutant target and wildtype control templates. To overcome this problem, delayed pyrophosphorolysis activated polymerization (delayed-PAP) was developed which can delay product accumulation of the wildtype control to a much later time or cycle by up to 15 cycles or by 30,000 folds. In the multiplex format, delayed-PAP is particularly useful to amplify not only the wildtype control but also mutant target templates accurately and consistently in the minimal-copy-ratio situation.

  • 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.
