Full-Length mRNA Sequencing-Nanopore

While NGS-based mRNA sequencing serves as a versatile tool for gene expression quantification, its reliance on short reads restricts its efficacy in complex transcriptomic analyses. Nanopore sequencing, on the other hand, employs long-read technology, enabling the sequencing of full-length mRNA transcripts. This approach facilitates a comprehensive exploration of alternative splicing, gene fusions, poly-adenylation, and the quantification of mRNA isoforms.

Nanopore sequencing relies on nanopore single-molecule real-time electrical signals. Guided by motor proteins, double-stranded DNA binds to nanopore proteins embedded in a biofilm, unwinding as it passes through the nanopore channel under a voltage difference. The distinctive electrical signals generated by different bases on the DNA strand are detected and classified in real-time, facilitating accurate and continuous nucleotide sequencing. This innovative approach overcomes short-read limitations and provides a dynamic platform for intricate genomic analysis, including complex transcriptomic studies.

Platform: Nanopore Promethion P48

Service Details


Demo Results

Featured Publications


●  Capture of poly-A mRNA followed by cDNA synthesis and library preparation

●  Sequencing of the full-length transcripts

●  Bioinformatic analysis based on alignment to a reference genome

●  Bioinformatic analysis includes not only expression at gene and isoform-level but also analysis of lncRNA, gene fusions, poly-adenylation and gene structure

Service Advantages

 ● Quantification of expression at the isoform level: enabling detailed and accurate expression analysis, unveiling change that may be masked when analysing the whole gene expression

 ● Reduced Data Demands: In comparison to Next-Generation Sequencing (NGS), Nanopore sequencing exhibits lower data requirements, allowing for equivalent levels of gene expression quantification saturation with smaller amounts of data.

 ● Higher accuracy of expression quantification: both at gene and isoform level

 ● Identification of additional transcriptomic information: alternative polyadenylation, fusion genes and lcnRNA and their target genes

 ● Extensive Expertise: with a track record of completing over 550 Nanopore full-length transcriptome projects and processing over 7700 samples, our team brings a wealth of experience to every project.

 ● Post-Sales Support: our commitment extends beyond project completion with a 3-month after-sale service period. During this time, we offer project follow-up, troubleshooting assistance, and Q&A sessions to address any queries related to the results.
