Tecan and Oxford Nanopore build new alliance
The collaboration aims to create automated and fully compatible nanopore sequencing library preparation for any-length fragments of native DNA/RNA
26 Apr 2023
The Tecan Group and Oxford Nanopore Technologies plc have announced their collaboration to drive easier high-throughput nanopore library preparation in an automated, hands-free fashion. The result is a fully walkaway automated workflow for Oxford Nanopore’s Ligation Sequencing Kit XL V14 protocol (LSK114) with Tecan’s DreamPrep® NGS solutions. The LSK114 protocol allows for any fragment length of DNA to be sequenced, which can range from cell-free DNA to amplicons to any length DNA fragments, from 200 base pairs to more than 100kb or even Mb. This is a major advance over traditional sequencing platforms and protocols that can only sequence short fragments typically in the range of 300 to 600 base pairs.
Sequencing native, long fragments of DNA is beneficial to generate more comprehensive insights into the genome – which often contain methylation, repetitive patterns of sequences or larger-scale genetic variants – as well as reaching parts of the genome that cannot be resolved by using traditional short read technologies in the same single sequencing run. Having complete genome assemblies is necessary to ensure better understanding of chromosome function, human disease, and genomic variation, which will translate in future to better prediction and management of diseases. Therefore, by combining highly reproducible automated library preparation of short and/or long fragments and high yields of genomic data, it becomes feasible to reliably identify a comprehensive map of genetic alterations, conduct accurate phasing, resolve repeated sequences, and measure DNA methylation, all in a single sequencing run. Being able to deploy the same workflow on shorter, native fragments, such as cell-free DNA, opens opportunities in methylation analysis and exploration of the complete cell-free DNA fragments in a sample, the ‘fragmentome’.
The collaboration between Tecan and Oxford Nanopore further expands Tecan’s growing portfolio of solutions for automated NGS library preparation. Tecan’s liquid handlers are compatible with all Oxford Nanopore devices, – from Flongle™ to PromethION™ 48, as well as the PromethION 2 (P2) Solo high-output sequencing device. This gives the potential to greatly expand access to accurate, fast and accessible sequencing for human genomics and other larger datasets.
Oxford Nanopore’s technology enables base-modification analysis to be performed alongside nucleotide sequencing on the same single read without the need to run multiple sequencing experiments. Therefore, unlike traditional technologies, no additional complex library preparation with (for example bisulfite sequencing for methylation) is required, and epigenetic modification analysis can be performed across the whole genome during the experiment. The integrated combination of Oxford Nanopore and Tecan technologies is intended to enhance true load-and-go DNA and RNA sequencing library preparation with proven liquid handling technology, reagent kits that are compatible with automation, and intuitive user interfaces that will allow set-up for walkaway library prep runs in the DreamPrep NGS.
