differently sized fluorescent RNA nucleotides, rUthioTP and rUpyrTP, and examined their transcription ability using T7 RNA polymerase. The smaller rUthioTP could be incorporated and extended to produce a corresponding RNA sequence, but rUpyrTP could not. We then used this rUthioTP‐containing fluorogenic transcription system, in conjunction with graphene oxide(GO), for the detection of miRNA 146a with high
在这项研究中,我们合成了两个不同大小的荧光RNA核苷酸rUthioTP和rUpyrTP,并使用T7 RNA聚合酶检查了它们的转录能力。较小的rUthioTP可以掺入并延伸以产生相应的RNA序列,但rUpyrTP不能。然后,我们将此含rUthioTP的荧光转录系统与氧化石墨烯(GO)结合使用,以高灵敏度和选择性检测miRNA 146a。转录的RNA产物和GO的这种组合是用于检测miRNA 146a的简单原位探测系统—既省时又更具成本效益。
