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.
•High quality score distributions: > 75% of bases with Q scores > 30 (2 x 150 bp)
•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
