Gain a comprehensive view of whole transcriptomes with high-output nanopore sequencing of full-length transcripts. Unambiguously identify and quantify isoforms and detect fusion genes. Discover new biology with the power of single-cell sequencing. Detect base modifications and avoid PCR bias with nanopore direct RNA sequencing — the only technology enabling direct sequencing of native RNA molecules.
What is whole-transcriptome sequencing?
Whole-transcriptome sequencing enables the analysis of the RNA transcripts present in a sample from an organism of interest. The method provides a dynamic view of the cellular activity at the point of sampling, allowing characterisation of gene expression and identification of isoforms. However, accurate analysis of transcripts using traditional short-read sequencing technology can be challenging, as RNA samples must be fragmented, sequenced in short sections, then reassembled, leading to potential multi-mapping — where short sequencing reads align to multiple locations.
With long nanopore reads, full-length transcripts can be sequenced end-to-end, facilitating their accurate, unambiguous analysis. Researchers are using whole-transcriptome sequencing to shed light on developmental biology, study the mechanisms underlying diseases such as cancers, and identify potential future disease-associated biomarkers.
Why nanopore technology for whole-transcriptome sequencing?
Nanopore technology enables complete, isoform-level transcriptome characterisation — at up to single-cell resolution.
Using nanopore sequencing, you can:
- Characterise and quantify full-length transcripts
- Unambiguously identify splice variants and fusion transcripts
- Reveal gene expression heterogeneity with single-cell transcriptomics
- Explore epigenetic modifications through direct RNA sequencing
- Enhance viral identification from metagenomic samples
One platform — comprehensive analysis
Experimental approach to whole-transcriptome sequencing
Sequencing kits are available for the preparation of both RNA and cDNA libraries. The Direct RNA Sequencing Kit allows native RNA molecules — including base modifications — to be sequenced directly. Enabling high-output sequencing of whole transcriptomes from low input amounts, the cDNA-PCR Sequencing Kit is ideal for identifying and quantifying full-length transcripts at the isoform level.

Analysis techniques for whole-transcriptome sequencing
Oxford Nanopore provides end-to-end bioinformatics workflows for the analysis of whole transcriptomes. The workflow wf-transcriptoms enables de novo or reference-guided transcript assembly from either cDNA or direct RNA reads, and provides differential gene expression and differential transcript usage analysis. For single-cell transcriptome analysis, the workflow wf-single-cell, a research pipeline, provides outputs including barcode and unique molecular identifier (UMI) tags, gene x cell expression matrices, and cell x transcript expression matrices. Both workflows are available in EPI2ME Labs.
