Any idea if the HS4000/5000 are using 4-color or 2-color chemistry? -
I think that's Nextseq only?
Looks to me like they've just stuck HiseqX-style flowcells in the 2500 system.Comment

Except that I'm pretty sure the X-series do use 2-dye chemistry, the same as NextSeq...Comment

I am not going to hold my breath though.Comment

Can't find any literature that says anything other than the Nextseq uses 2 colors. In fact, isn't this why the Nextseq currently has GC problems? Haven't heard anything about that with the HiseqX...Originally posted by Brian Bushnell View PostComment

New toys for one person is a funding/migration headache for another. Especially if there is no upgrade path. :-(Comment

This http://blog.illumina.com/blog/illumi...eq-4000-system says the 4000 uses 4-color.
This http://www.illumina.com/content/dam/...0-2014-057.pdf says that 1 flowcell does 50 transcriptomes per run at 50M reads each, so that is >300M reads per lane. Looks faster as well, if the longest run time is 3.5 days (not sure if that would be for 1x150bp or 2x150bp).Providing nextRAD genotyping and PacBio sequencing services. http://snpsaurus.comComment

There are data from PCR-free, RNA-Seq and NRC libraries sequenced on HiSeq 4000 in BaseSpace.Comment

Heard from someone that the cluster and reagent kits are similar in price to current Hiseq 2000 reagents, which would mean the price per read is quite a bit lower.Providing nextRAD genotyping and PacBio sequencing services. http://snpsaurus.comComment

#SNPsaurus:
I assume it will be 2x 150 bp in 3.5 days.
2.1 to 2.5 billion clusters per flow cell, in a 2x150 bp run is 630 - 750 Gb.
With a speed >200Gb per day a 2x 150 bp run will take 3.5 days.
I wonder if we can upgrade the 2500 V4 machine to a 4000 version...Comment

It looks to me that the 3000/4000 only accept 8 lane flow cells (high-output). If true then the trade off for throughput is flexibility.Comment

Ditto. I think supporting the patterned flow-cells would require too much of a reworking of the guts...Originally posted by GenoMax View Post

The immune system’s power comes from its genetic diversity, allowing myriad threats to be neutralized through first recognizing foreign antigens. That diversity is also what makes the immune system so difficult to study. Recent advances in sequencing technology and computational biology, however, are giving researchers new tools to understand immune responses and immune-related diseases in greater detail.
This convergence of genetics, immunology, and computation...09-01-2026, 05:41 AM
