8 HiSeq 2000/2500 – 100-160mln single end sequencing reads per lane. What type of sequencing should I choose for the Illumina sequencing project?HiSeq 2000/2500 – mln single end sequencing reads per lane.- ChIPseq – Single End 50 cycles (2-3 human samples per lane)- RNAseq – Single End 50 cycles (2-3 human samples per lane)If you are interested in splicing variants and fusion genes both Single End 100cycles and Paired End 2x50cycles will be better option for you.Whole Genome Sequencing – Paired End 2x100cycles (2-3 lanes per genome)Exome Capture - Paired End 2x100cycles (4 samples per lane)MiSeq – 3-7 mln single end sequencing reads per lane. Custom projects , fast turnaround.Metagenomics - 16S profile – Paired End 2x150cycles up to 24 samples per lane.Whole Microbial Genome Sequencing - Paired End 2x150cycles
9 SHORT READ PLATFORMS at UNC HiSeq 2000Initially capable of up to 600Gb per run in 13 days.Cost of resequencing one human genome:Now UNC PI - (30x coverage) about $6,000Now for outside of UNC - (30x coverage) about $9,000HiSeq 2500Initially capable of up 100Gb per run in 27hours.Cost per genome - ???
10 MiSeq Small capacity system. PE 2x150cycles in 27hours. PE 2 x 250bp coming soon – error rate for read 1 – less than 1%; read 2 about 1.2%.In preparation – PE 2 x 400bp – error rate for read1 about 2%; read 2 about 4%.In preparation – Longer insert size possible 1.5kb

14 Personal Genome Machine – Ion Torrent (life technologies) Three types of semiconductor chips:314 – 20MbMb318 – 1GbRead length depends on base composition bp (200cycles)System is enabled for Paired End 2x100cyclesThe fastest sequencing system on the market.How it works:H+ ion is released during base incorporation. Individual polymerases attached to beads are positioned in tiny wells that rest on a tiny pH meter.Recommendation:Resequencing applications which require fast turnaround of samples- Amplicons (PCR products)Small and medium size genomesCustom DNA capture applications

25 Genia TechnologiesVery early stage announcement – Backed by Life Technologies (at least 1 year away)Describe system as a cross between Ion Torrent and Oxford NanoporeElectronic “Active Control” technology enables highly efficient nanopore-membrane assembly and control of DNA movement through the channelInitially used α-Hemolysin and claimed 98% raw accuracy with that but now are using an undisclosed pore for further development.Claim sensitivity 1-2 orders of magnitude greater than Oxford Nanopore.Ramping up pore density to 100K pores/chip by end of 2012.Plan to market a mobile reader for <$1K and per sample costs <$100Plan early access in late 2012, commercial shipment 2013
