  三唑连接的DNA作为第一链cDNA合成中的引物替代品

  摘要：

  磷酸消除的非天然寡核苷酸可作为mRNA逆转录反应中的引物替代物。尽管在替代物中存在非天然三唑键，但逆转录酶通过转录mRNA的互补序列有效地延长了引物3'下游的cDNA序列。与参考天然寡核苷酸的结构活性比较表明，含有三唑键的替代物具有更好的引发活性。非天然连接还可以保护转录的cDNA免于与5'-核酸外切酶的消化反应，并使我们能够去除未知来源的噪音转录本。

  A phosphate‐eliminated nonnatural oligonucleotide serves as a primer surrogate in reverse transcription reaction of mRNA. Despite of the nonnatural triazole linkages in the surrogate, the reverse transcriptase effectively elongated cDNA sequences on the 3′‐downstream of the primer by transcription of the complementary sequence of mRNA. A structure–activity comparison with the reference natural oligonucleotides
