Some clarifications about Ion Torrent PII and NextSeq 500 2

Yesterday’s Ion Torrent Proton PII™ and Illumina NextSeq 500™ post certainly got a reaction from several quarters, including detailed pricing information about the 1x75bp format for the high-throughput configuration on the consumables. Instead of making edits to the original here are some clarifying points, as it is clear that Illumina […]

Error, alignment, and the myth of the complete genome

The myth of the complete genome is something that is not commonly known to active observers of genomic technologies. (The term ‘active observer’ is from the point of view of one with varying degrees of background in the biological sciences, and is in noway an aspersion.) The ‘first draft’ of […]

What’s so special about single molecule sequencing? 2

A few days ago I reviewed in brief the history of Helicos Biosciences (HCLS), a company that held out the promise of single molecule sequencing, but failed to deliver on several fronts to the next-generation sequencing market. (This would include accuracy, throughput per dollar, and ease of use / reliability […]

Helicos Single Molecule Sequencing – A Pioneer 8

The next-generation sequencing market continues its downward trajectory – routinely violating Moore’s Law by an estimated 3x, the cost per megabase curve started to significantly bend downward around 2007 when the Solexa 1G started selling in volume, and gave the 454 GS20 (as it was known then) the first competition […]

Next-Generation Sequencing – its historical context

Even though the history of next-generation sequencing is short (the 454 GS20 came out in 2005, the Solexa 1G in 2007, and the SOLiD 2 in 2008), there is a robust genomic revolution going on, and a fierce battle in the marketplace with plummeting costs and soaring throughput. Whether Moore’s […]
