Direct RNA sequencing (dRNA-seq) simultaneously enables the detection of RNA modifications and characterization of full-length transcripts. In principle, full-length native RNA molecule is translocated through the nanopore by a motor protein while a sensor measures ionic current shifts. Then, the current shifts are interpreted by an algorithm that turn out to RNA sequence. Currently, the standard protocol of dRNA-seq provided by Oxford Nanopore Technologies (ONT) allows to directly ligate and sequence only polyadenylated RNA (poly(A) RNA). Here, we describe a method of dRNA-seq that can be applied for both poly(A) RNA and non-poly(A) tailed-RNA.
直接 RNA 测序（dRNA-seq）可同时检测 RNA 修饰和全长转录本的特征。从原理上讲，全长的天然 RNA 分子在通过纳米孔时被马达蛋白转运，同时传感器测量离子电流的变化。然后，算法将电流变化解释为 RNA 序列。目前，牛津纳米孔技术（ONT）提供的 dRNA-seq 标准方案仅允许直接连接和测序多聚腺苷酸化 RNA（poly(A) RNA）。在这里，我们描述了一种可应用于多聚腺苷酸化 RNA 和非多聚腺苷酸化 RNA 的 dRNA-seq 方法。
