DNA Sequencer and additional system components for Next-Generation Sequencing System
· Multiple flow cell and reagent configurations enable sequencing of 20–120 Gb per run.
· Up to 400 M single read clusters (800 M paired-end reads) passing filter in the High Output configuration enable up to 120 Gb per run.
· Up to 120 Gb of output allows sequencing of a 30× human genome in a single run.
· Up to 120 Gb of high-quality filtered bases in 29 hours on the sequencer (2 × 150 bp reads) or up to ~100 Gb per day.
· No need for emulsion PCR—amplification is performed directly on the instrument.
· Fully automated onboard cluster generation enables prepped libraries to be loaded directly onto the instrument.
· Single instrument performs clonal amplification, sequencing, paired-end turn and primary data analysis (e.g. base calling).
· Scalability from 20–120 Gb in a single run to support a broad range of applications and study sizes
· Desk-top instrument: W×D×H: 58.5 cm × 53.4 cm × 63.5 cm (23.0 in × 21.0 in × 25 in).
· Weight: 83 kg (183 lbs).
· 12 light-emitting diodes at 520 nm, 650 nm.
· Instrument footprint requires less than two square feet of benchtop space.
· Alignment, variant calling, and reporting are supported in BaseSpace.
· Resulting DNA clusters are sequenced using ‘sequencing by synthesis’ method with reversible terminator chemistry.
· Integrated cluster generation provides automated clonal amplification of single molecules randomly distributed on a glass surface.
· Accurate sequencing of homopolymers.
· Real-time analysis processing automatically produces image intensities and quality-scored base calls directly on the instrument computer.
· Sequencing reactions are performed on the surfaces of a multichannel flow cell.
· A single operator can amplify up to 24 samples on a single channel in ~2 hours using a single instrument.
· Two flow cell formats and multiple reagent configurations enable data output from 20–120 Gb in a single run.
· A simple workflow and quick run time to enable the fastest desktop sequencing of exomes, transcriptomes, and whole genomes.
· Massively parallel sequencing technology for genetic analysis and functional genomics.
· Suite of dedicated flow cell and reagent configurations to generate up to 400 million clusters passing filter (up to 120 Gb).
· The system includes an option to integrate with BaseSpace genomic computing environment to store, analyze, and share genomic data, available as either a cloud or an onsite deployment (i.e. BaseSpace Onsite system).
| • | Runs, including onboard cluster generation, in 12–30 hours. |
| • | Fully automated paired-end sequencing. |
| • | 10 minutes hands-on time for run set up (amplification, paired-end sequencing). |
| • | Hands-free, completely automated, on-instrument paired-end sequencing. |
| • | Supports up to 2 × 150 bp read length. |
| • | Accurate variant detection enabled by sequencing by synthesis chemistry: Competitive nucleotide addition with a reversible terminator technology allow for highly accurate sequencing, even through homopolymeric regions. |

| • | Up to 400 M single reads to enable gene expression profiling and cytogenetic applications |
• Number of reads per run:
· Up to 400 million reads per run (e.g. clusters passing filter).
• Throughput per run:
· 100–120 Gb data per 2 × 150 bp run using High Output flow cell and reagents
· Sequencing flexibility
· Set-up options include single-read or paired-end runs
· Flow cell options (e.g. Mid or High Output flow cells) can be used to select data output levels
· Read-length is fully adjustable up to 300 base pairs
| • | 12 light-emitting diodes at 520 nm, 650 nm |
| • | Reagent compartment has capacity for one reagent cartridge containing reagents for cluster generation, paired-end chemistry, and up to 300 cycles of sequencing |
| • | Reagents arrive pre-mixed in an integrated, RFID enabled, reagent cartridge |
| • | Libraries are loaded directly into the sequencer through an onboard template loading station |
| • | System is a single flow cell system |
| • | Each flow cell is a substrate with a single channel that can be imaged on both the top and bottom surfaces |
| • | Flow cells are auto-positioned |
| • | Flow cells are keyed such that there is only one correct orientation |
| • | Instrument control computer is integrated in the sequencer—no additional computer purchase is required |
| • | Sequence output contains accurate base calls and qualities derived directly from intensity data and not from a reference, sequence-based, or multiple-color encoding scheme |
| • | Produces FASTQ, BAM, VCF, and txt formatted files for maximum compatibility with third-party downstream software packages |
| • | Automated transcriptome analysis with the widely used TopHat/Cufflinks suite of tools |
| • | Works with consumer-grade internet bandwidth (~1.5 Mbps) |
| • | Up to 6 servers can be connected to each other to increase processing power and storage while keeping a single software environment |
