We present a detailed protocol for sequencing full-length mRNA isoforms using the Oxford nanopore long-read sequencing technology. We describe steps for poly(A) RNA isolation, library preparation, and cDNA size selection. We then detail procedures for sequencing and processing and a computational framework to identify exon couplings and assign mRNA 5' ends and 3' ends to each other. Our approach enables the identification of links between transcription initiation and co-transcriptional RNA processing events. For complete details on the use and execution of this protocol, please refer to Alfonso-Gonzalez et al..
我们提出了一个使用牛津纳米孔长读测序技术对全长 mRNA 异构体进行测序的详细方案。我们描述了聚(A)RNA 分离、文库制备和 cDNA 大小选择的步骤。然后,我们详细介绍了测序和处理的程序,以及一个计算框架,用于识别外显子连接,并将每个 mRNA 的 5' 端和 3' 端彼此对应。我们的方法能够识别转录起始与共转录 RNA 加工事件之间的联系。有关此方案的使用和执行的完整详细信息,请参阅 Alfonso-Gonzalez 等人的研究。
