Choosing the Right NGS Sequencing Instrument for Your Study

⬅️ NGS Handbook

The right sequencing instrument for your study depends on your project goal. Setting aside turnaround time and price, it essentially comes down to the numbers of reads and read length you need for your experiment. Below, we've described and compared metrics for each of the instruments available. If you’re new to high-throughput sequencing and have questions about how you should design your sequencing run, fill out our free consultation form and we'll get in touch with you to help.

Apart from some minor considerations Genohub's NGS Matching Engine makes it very easy to see what instruments fit your project best. Simply enter your specifications and instantly see services that match your output requirements.

Illumina

Illumina instruments are versatile and ideal for a variety of sequencing applications, including assembly, resequencing, transcriptome, SNP detection and metagenomic studies. The HiSeq, Nextseq and GAIIx instruments are well suited for analyzing large animal or plant genomes. High level multiplexing of samples is possible when analyzing species with a smaller genome size. The HiSeq X instrument, released by Illumina in early 2014, has been been specifically designed for sequencing of whole genomes. The Illumina MiSeq outputs significantly fewer reads (Table 1), but its read lengths are significantly longer, making it ideal for small genomes, sequencing long variable domains or targeted regions within a genome. In fact, out of all the Illumina instruments, the MiSeq is best suited for amplicon-seq, 16S and other low diversity read based applications. The MiSeq Control Software (MCS) now allows users to use as little as 5% PhiX DNA spike-in to successfully sequence low-diversity samples. Other instruments, including the HiSeq and GAIIx still require at least 20-50% PhiX and are less suited for low diversity samples. The NextSeq 500, released in March of 2014, uses a two channel SBS sequencing process, likely making it even less suited for low diversity amplicons. As of 4/2014, Illumina has not performed significant validation or testing using low diversity samples on the NextSeq 500. It is not expected that the NextSeq 500 instrument will perform better than the HiSeq for these sample types. The only other major limitation of Illumina instruments compared to others in this list is their relatively short reads (2x300 is currently the longest MiSeq paired end read length).

Oxford Nanopore

Oxford Nanopore instruments are ideal for sequencing short to ultra-long fragments of native DNA or RNA and can be used for various applications. The main limitation of Oxford Nanopore sequencing is the comparatively lower read accuracy compared to short read sequencing. The relatively higher insertion and election error rates make Nanopore sequencing less optimal for single nucleotide variation/polymorphism (SNV or SNP) detection, unless you can obtain high coverage. Oxford Nanopore has improved on this limitation with the latest R10.3 chemistry, which allows for higher throughput and capture and improved raw accuracy to support enhanced variant calling.

Starting from the smallest instrument, the Flongle is an adapter for the MinION or GridION platforms and is best for amplicon sequencing, small panel/targeted sequencing, quality testing for a pilot run before a larger sequencing experiment, and running single samples on demand rather than multiplexing. The MinION is a larger, portable instrument and is best used for whole genomes, whole exomes, metagenomes, whole transcriptomes (cDNA), smaller transcriptomes (direct RNA), targeted sequencing and multiplexing for smaller samples. The GridION is a benchtop instrument designed to run up to five MinION or Flongle Flow Cells, each of which can be independently controlled in real time. The GridION is ideal for larger genomes, whole transcriptomes (direct RNA or cDNA) and a higher number of samples. The PromethION is the largest instrument and is used for high-coverage sequencing. At this level, each flow cell delivers the lowest price per Gb for nanopore sequencing, making it ideal for larger genomes, population-scale experiments, highly multiplexed small genomes or targeted regions and whole transcriptomes (direct RNA or cDNA).

Ion Torrent

The Ion PGM (Ion Torrent), is ideal for amplicons, small genomes or targeting of small regions within a genome. Its low throughput makes it ideal for smaller sized studies. The Ion Proton however is capable of generating significantly larger outputs (Table 1) making sequencing of transcriptome, exome and medium sized genomes possible.

Pacific Biosystems

The PacBio RS/RS II breaks the mold of other short reads high throughput sequencing instruments by focusing on length. The reads, averaging ~4.6 kb are significantly longer than other sequencing platforms making it ideal for sequencing small genomes such as bacteria or viruses. Other advantages include its ability to sequence regions of high G/C content and determine the status of modified bases (methylation, hydroxymethylation), eliminating the need for chemical conversion during library preparation. The instrument’s low output of reads prevent it from being useful for assembly of medium to large genomes.

Roche 454

The Roche 454 FLX+ is typically used in studies where read length is critical. These include de novo assemblies of microbial genomes, BACs and plastids. Its long read length has made it a favorite of those examining 16S variable regions and other targeted amplicon sequences. The lower output of the FLX and FLX+ instruments makes it less cost-effective for transcriptome or larger genome studies. Roche has announced that it will stop manufacturing the 454 in 2015 and end servicing in mid-2016.

Element Biosciences

Element Biosciences offers the AVITI System, a sequencing platform utilizing Avidite sequencing, a novel chemistry that utilizes rolling circle amplification (RCA) to minimize amplification errors. This technology enables rapid, high-throughput sequencing with long read lengths. The AVITI is particularly well-suited for whole genome sequencing, transcriptomics, and metagenomics studies where long reads and high accuracy are crucial for comprehensive analysis. It is also cost-effective for small or medium labs who would like to run their own sequencing but can’t afford a large Illumina instrument, as Element Biosciences offers a fair upfront cost for the AVITI and promises customers that the price of reagents will never change for the life of their AVITI System.

Complete Genomics

Complete Genomics offers a range of sequencers utilizing DNBSEQ (DNA Nanoball Sequencing) technology. This method involves amplifying DNA fragments into nanoballs, increasing signal-to-noise ratio and improving sequencing accuracy. Complete Genomics’ platforms cater to a wide spectrum of sequencing needs. The DNBSEQ-T7, for example, is a high-throughput sequencer ideal for large-scale genome, exome, and transcriptome sequencing projects due to its rapid output and cost-efficiency. For medium-scale projects, the DNBSEQ-G400 offers a balance of speed and accuracy along with on-board primary data analysis that makes it suitable for a diverse set of projects. Then for small-scale projects or projects that require on-location sequencing, the DNBSEQ-E25 is a lightweight, compact system that can be used anywhere and is most useful for pathogenic microorganism detection and small genome sequencing.

Singular Genomics

Singular Genomics' G4 sequencer employs a 4-color rapid sequencing-by-synthesis (SBS) chemistry that includes novel nucleotides, enzymes and methods. A strength of the G4 is that researchers can simultaneously run 4 flows cells with 4 independent lanes each. This grants a high amount of flexibility and makes it well-suited for many different types of sequencing, including RNA, single-cell RNA, exome, target enrichment, metagenomic, and whole genome sequencing.

Ultima Genomics

Ultima Genomics is pioneering a disruptive sequencing technology that aims to drastically reduce the cost of sequencing to $1 per Gb. Their UG 100 platform utilizes open silicon wafers instead of flow cells and a unique technology, where automated rotational motion is used to deliver reagents and produce images. This platform is expected to be ideal for a variety of sequencing projects, where cost-effective, high-throughput sequencing is essential, such as RNA, methylation, single cell, whole genome, and exome sequencing.
