    多种大小的方法可将高度荧光的非天然核苷酸掺入并延伸到DNA中。
    摘要:
    我们准备了一系列大小不一的非天然核苷酸,它们均基于荧光(dApyrTP,dUpyrTP,dUantTP,dUthiTP)和淬灭(dUazoTP)单元,以及具有小的官能团(dAethTP,dAoctTP,dUethTP,dUiodTP)的核苷酸。脱氧腺苷和脱氧尿苷,并检查了它们在酶促掺入和扩展到DNA中的适用性。我们观察到引物延伸过程中掺入和延伸能力的大小依赖性(遵循dUiodTP = dUethTP = dUthiTP> dUazoTP> dUpyrTP> dUantTP的顺序)。该结果得到圆二色性(CD)光谱的支持,圆二色性光谱揭示了不同B型DNA结构的趋势,该结构取决于脱氧尿苷5位单元的大小(dUiodTP> dUethTP> dUthiTP> dUpyrTP)。从PCR产物。有趣的是,dUthiTP可以在引物延伸甚至PCR扩增过程中掺入并延伸到长DNA链中,CD光谱证实了稳定的二级B

    could not. This dUthioTP fluorescent nucleotide could be used for the detection of miRNA 24-3P, which is related PRRSV. This direct labeling system during rolling circle DNA amplification exhibited an increased fluorescence signal showing gel formation for the detection of miRNA 24-3P. This direct labeling system is a very simple and cost-efficient method for the detection miRNA 24-3P and also exhibited
    我们从噻吩,蒽和pyr中设计并合成了几种大小不同的荧光核苷酸,并筛选了它们在DNA滚环扩增过程中的掺入和延伸能力。基于噻吩的荧光核苷酸(dUthioTP)可以高度整合并延伸到滚环DNA产品中,而其他荧光核苷酸(dUanthTP和dUpyrTP)则不能。该dUthioTP荧光核苷酸可用于检测与PRRSV相关的miRNA 24-3P。在滚环DNA扩增过程中,这种直接标记系统显示出增加的荧光信号,表明用于检测miRNA 24-3P的凝胶形成。

    公开(公告)日:2022-07-19
    A method for determining the presence, absence or amount of two or more target polynucleotides in a sample comprising additional components, the method comprising: (i) contacting the sample with a panel of two or more probes under conditions suitable for hybridisation of the target polynucleotides to the probes, wherein: (a) each probe comprises a non-hybridisation region and a hybridisation region that specifically hybridises to one of the target polynucleotides to form a hybridised probe; and (b) the hybridisation region of a probe of the panel comprises one or more non-natural nucleotides; (ii) contacting the sample prepared in step (i) with a transmembrane pore through which a single stranded polynucleotide but not a double stranded polynucleotide can pass and applying a potential difference to the transmembrane pore such that the hybridised probes in the sample interact with the pore; (iii) measuring current blockades having a duration within a defined window, wherein: (a) the one or more non-natural nucleotides present in the hybridisation region of the probe increase or decrease the duration of the current blockade due to the probe hybridised to its target polynucleotide such that the proportion of current blockades that occur within the window due to the interaction of the hybridised probes with the pore is increased compared to when the corresponding one or more natural nucleotides are present in the hybridisation region; and (b) each hybridised probe gives rise to a current blockade indicative of that probe; and (iv) correlating the measured current blockades with the probes, thereby determining the presence, absence or amount of the two or more target polynucleotides in the sample.
