RNA and gene expression analysis using direct RNA and cDNA sequencing
Unlike traditional RNA-Seq techniques, long nanopore RNA sequencing reads allow for accurate quantification and complete, full-length characterisation of native RNA or cDNA without fragmentation or amplification — streamlining analysis and removing potential sources of bias. Direct RNA sequencing also enables the identification of base modifications alongside nucleotide sequence.
- Characterise and quantify full-length transcripts — up to single-cell resolution
- Get faster access to results with real-time analysis and bespoke tools
- Reduce bias with PCR-free protocols
- Explore epigenetic modifications through direct RNA sequencing
- Scale to your needs using Flongle, MinION, GridION or PromethION
How will you use nanopore technology?
Quantify and study differential gene expression
Identify fusion transcripts
Characterise RNA viruses and viral epidemiology
Detect base modifications
The high yields of long, full-length reads delivered by nanopore sequencing allow unambiguous characterisation and quantification of transcript isoforms – providing a true reflection of gene expression. Low input amounts combined with rapid, streamlined workflows enable highly sensitive gene expression analysis, even from single cells.
- Full-length transcripts — unambiguous identification of splice variants and fusion transcripts
- Accurate transcript and isoform quantification
- Eliminate PCR bias using direct cDNA or direct RNA sequencing
- Detect base modifications alongside nucleotide sequence using direct RNA
- Easy identification of anti-sense transcripts and lncRNA isoforms
‘Our results show that not only can we identify complex isoforms, but also quantify their expression, at the single cell level’
Jeremy Wang: Classification of pediatric acute leukaemia using full-length transcriptomics
With nanopore sequencing, read length is equal to fragment length, enabling routine analysis of long, full-length transcripts. This minimises the impact of multimapping — where short sequencing reads align to multiple locations — and allows complete characterisation of transcript isoforms and chimeric transcripts. Phasing can also be determined, providing easy differentiation between clonal and polyclonal variants.

Redefining the transcriptional complexity of viral pathogens using direct RNA sequencing
Base modifications such as m6A can modulate the activity and stability of RNA molecules, and have been linked to multiple human diseases and antimicrobial resistance. Unlike traditional technologies, nanopore technology can sequence native RNA molecules. With no requirement for amplification or reverse transcription, nanopore sequencing allows direct identification of base modifications alongside the nucleotide sequence — no chemical or protocol adaptations are required. The facility to sequence full-length transcripts enables modifications to be unambiguously assigned to specific isoforms.
