NextSeq 500’s new chemistry described

By | January 17th, 2014|Categories: Next-generation sequencing|15 Comments

NextSeq 500 uses a two-colour chemistry rather than the original four-colours. This makes a massive difference to the complexity of producing reagents, the instrumentation and the computation; all are effectively reduced by a factor of two. So how does it work?Update 290114: I got confirmation […]

How much does NGS cost: a logical puzzle

By | November 30th, 2013|Categories: Uncategorized|8 Comments

At our recent institute symposium I added an additional graphic to try and get people thinking about how much their sequencing costs.Can you work it out: Below are six pairs of circles representing genome, methylome, RNA-seq (GX), ChIP-seq, Exomes and amplicons, size is proportional to […]
