Whole-genome sequencing

Generate reference-quality microbial, human, animal, and plant genome assemblies with long nanopore sequencing reads (reads >4 Mb demonstrated). The greater overlap offered by long reads enhances genome assembly by providing longer continuous, unambiguously assembled sequences, resulting in fewer contigs. Accurately resolve structural variants and repeat regions, and characterise base modifications (e.g. methylation), fusion genes, and haplotype phasing, with PCR-free nanopore sequencing data.


What is whole-genome sequencing?

Whole-genome sequencing aims to provide complete analysis of an organism’s genome. The technique allows subsequent reassembly of the genome sequence and identification of novel variants and genomic structures that would be missed by targeted sequencing approaches. Until recently, routine application of whole-genome sequencing was limited due to its comparatively high cost; however, the development of modern sequencing techniques, such as nanopore sequencing, now enable every researcher to benefit from comprehensive and cost-effective whole-genome characterisation of their samples of interest.

Whole-genome sequencing has been instrumental in many research areas, from identifying novel disease-associated variation in humans, plants, and animals, to tracking microbial outbreaks such as SARS-CoV-2.

Why nanopore technology for whole-genome sequencing?

Nanopore technology delivers the most comprehensive whole-genome analysis available on a single platform.

Using nanopore sequencing, you can:

  • Resolve structural variants, repeat regions, and phased haplotypes with ultra-long reads
  • Generate reference-quality, telomere-to-telomere genome assemblies
  • Eliminate amplification bias and identify epigenetic modifications as standard
  • Streamline your workflow with 10-minute library prep and real-time data streaming
  • Scale to your needs — using Flongle, MinION, GridION, or PromethION

Experimental approach to whole-genome sequencing

A wide range of library preparation kits are available to suit all whole-genome sequencing requirements. Amplification-free kits allow direct, long-read sequencing of native DNA, eliminating the potential for PCR bias and enabling the detection of base modifications (e.g. methylation) alongside the nucleotide sequence. Amplification-based kits are also available, enabling whole-genome sequencing from low input amounts or poor-quality DNA (e.g. FFPE samples).
