If you want to know more read the 2500 app note on Ilumina's website, although the Yield figures in the table appear to be incorrect!
There has been much less noise about the likely cost of the data from the rapid run "MiSeq on steroids" format. A recent post on SEQanswers is the first sniff of HiSeq 2500 pricing, although it may not be accurate. It suggests a PE cluster kit will cost $1225 and a 200 cycle SBS kit will be $1690.
I used these figures to get to the possible cost per lane of a HiSeq 2500 run:
- PE100 multiplexed: £900 or $1500
This compares incredibly well to the normal output. In fact to me it looks like HiSeq 2500 rapid run mode could be the best choice for core labs like mine as it offers incredible flexibility as a two lane flowcell is quicker to fill up than an 8 lane one. And five dual-flowcell rapid runs will take less time and generate the same data as a dual-8-lane-flowcell standard run. The cost per Gb is going to be a little higher but many users will see this as a fair trade-off for faster turn-around-times.
The HiSeq 2500 rapid runs will also use on-instrument clustering. Exactly how this is going to fit inside the instrument with the available fluidics is not completely clear. I'd expect that we will have to run both positions in the same configuration using the current PE reagent rack.
Whether Illumina are able to really turn HiSeq 2500 into "MiSeq on steroids" and up read lengths to the 687bp presented at AGBT is still to be seen. They might have to if Ion Torrent can push their read-lengths out to current 454 lengths.
The competition: The latest specs from Life suggest that the Proton II chip will generate 20x coverage of a genome (and analyse in a day). However it is not clear if the run time will be longer or multiple chips will be run, current times are 2 hours per chip. A 20x genome in 2 hours would be great, but I don't think we can expect quite that from Life just yet. There is also a video of the first 4 Proton's to be installed (at BCM); "install to sequence in 36 hours" although the video only shows samples being centrifuged before loading and no real sample prep.
What's next: One thing I am happy to predict is that advances in sequencing technology are not going to stop any time soon, and when ONT come out from under their invisibility cloak we might finally get a peek at some data that shows what tomorrow holds.
