Nanopore Direct RNA Sequencing

Nanopore direct RNA sequencing is a third generation sequencing (TGS)-based method to sequence the whole transcriptome of cells or tissues. We provide nanopore direct RNA sequencing to help you resolve structural variants and repetitive regions, enhance metagenomic identification of closely related species, sequence entire microbes in single reads-in real-time.


Nanopore direct RNA sequencing is one kind of long-read sequencing, emerged in 2011, provided by Oxford Nanopore Technologies (ONT). Nanopore direct RNA sequencing provides a direct, real-time sequencing of long RNA fragments. Nanopore direct RNA sequencing using nanopore inserted in an electrical resistant membrane, there are 2048 nanopores on the membrane. As the RNA fragments pass through the nanopores, the bound polymerase or enzyme can attach to the RNA, the electrical current change was measured, indicating a specific RNA sequence. Nanopore direct RNA sequencing allows ultra-long reads, the longest fragment is close to 1 million bp. Advantages of Nanopore direct RNA sequencing include: 1) direct, real-time analysis; 2) allowing ultra-long kilobases in a continuous read; 3) pocket-sized sequencers are portable with low cost.

We provide Nanopore direct RNA sequencing services for identifying new genes, transcripts, and alternative splicing events, resolving structural variants and repetitive regions, enhancing metagenomic identification of closely related species, sequencing entire microbes in single reads-in real-time. Nanopore direct RNA sequencing also performs rapid pathogen detection and strain characterization, for example, it can be used to screen Ebola and Lassa virus outbreak in Africa.
