Rapid access to results

Offering comprehensive, real-time insights into the genomics of infectious diseases — from pathogen identification and antimicrobial resistance (AMR) profiling to the assembly of high-quality genomes and variant identification — nanopore sequencing delivers immediate access to the critical genomic epidemiology data required to effectively control infectious disease outbreaks. Sequence in the lab or at sample source at a scale that suits your needs, with powerful portable and high-throughput nanopore sequencing devices.

AmPORE-TB

AmPORE-TB is a research workflow that delivers rapid characterisation of mutations associated with antimicrobial resistance in Mycobacterium tuberculosis, species identification, and lineage identification in a single assay, directly from sputum samples.

Combining fast library preparation with on-demand nanopore sequencing and hands-off, comprehensive analysis onboard the GridION AmPORE-TB device, the AmPORE-TB workflow can take as little as six hours for same-day results.

The GridION AmPORE-TB device, installed with the AmPORE-TB data analysis software, will be distributed by bioMérieux (Q-GRD-MK1-ATB).

This workflow performs filtering, genetic variant calling, and sequence alignment to the CDC influenza reference. The analysis can be run using a fully automated, point-and-click user interface or via the command line.

Legacy short-read sequencing

    • Generate complete, high-quality genomes with fewer contigs and simplify de novo assembly
    • Resolve genomic regions inaccessible to short reads, including complex structural variants (SVs) and repeats
    • Analyse long-range haplotypes, accurately phase single nucleotide variants (SNVs) and base modifications, and identify parent-of-origin effects
    • Sequence short DNA fragments, such as amplicons and cell-free DNA (cfDNA)
    • Sequence and quantify full-length transcripts to annotate genomes, fully characterise isoforms, and analyse gene expression — including at single-cell resolution
    • Resolve mobile genetic elements — including plasmids and transposons — to generate critical genomic insights
    • Enhance taxonomic resolution using full-length reads of informative loci, such as the entire 16S gene
    • Assembly contiguity is reduced and complex computational analyses are required to infer results
    • Complex genomic regions such as SVs and repeat elements typically cannot be sequenced in single reads (e.g. transposons, gene duplications, and prophage sequences)
    • Transcript analysis is limited to gene-level expression data
    • Important genetic information is missed
    • Eliminate amplification- and GC-bias, along with read length limitations, and access genomic regions that are difficult to amplify
    • Detect epigenetic modifications, such as methylation, as standard — no additional, time-consuming sample prep required
    • Create cost-effective, amplification-free, targeted panels with adaptive sampling to detect SVs, repeats, SNVs, and methylation in a single assay
    • Amplification is often required and can introduce bias
    • Base modifications are removed, necessitating additional sample prep, sequencing runs, and expense
    • Uniformity of coverage is reduced, resulting in assembly gaps
    • Analyse data as it is generated for immediate access to actionable results
    • Stop sequencing when sufficient data is obtained — wash and reuse flow cell
    • Combine real-time data streaming with intuitive, real-time EPI2ME data analysis workflows for deeper insights
    • Time to result is increased
    • Workflow errors cannot be identified until it is too late
    • Additional complexities of handling large volumes of bulk data
    • Sequence on demand with flexible end-to-end workflows that suit your throughput needs
    • Sequence at sample source, even in the most extreme or remote environments, with the portable MinION device — minimise potential sample degradation caused by storage and shipping
    • Scale up with modular GridION and PromethION devices — suitable for high-output, high-throughput sequencing to generate ultra-rich data
    • Sequence as and when needed using low-cost, independently addressable flow cells — no sample batching needed
    • Use sample barcodes to multiplex samples on a single flow cell
    • Bulky, expensive devices that require substantial site infrastructure — use is restricted to well-resourced, centralised locations, limiting global accessibility
    • High sample batching is required for optimal efficiency, delaying time to results
    • Lengthy sample prep is required
    • Long sequencing run times
    • Workflow efficiency is reduced, and time to result is increased
