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 […]
There has been a lot of publicity around the NextSeq 500 from Illumina, and it appears to have been designed to compete directly against Ion Torrent’s upcoming PII chip. Thanks to a visit to upstate New York last week, I met Dr. Sridar Chittur who told me how important it […]
Today Ion Torrent launches a neat product based upon a highly multiplexed technology called AmpliSeq, called the Ion AmpliSeq Exome, covering >97% of the CCDS regions. But before getting into the details, a little context is in order.
Earlier this year at the February AGBT Conference, a person from QIAGEN came over to the Ion Torrent suite and asked me a few questions about the Ion Proton and in particular the upcoming Ion Chef unit. (The Ion Chef for those not familiar with it can replace the OneTouch […]
Every mother-to-be who has what is considered an ‘at-risk’ pregnancy is informed of the risks to the fetus of a genetic abnormality. ‘At-risk’ can involve a long list of medical conditions (diabetes or cancer for example) or poor health choices (illegal drug use or smoking). Yet a common cause of […]
Immunology is a fascinating subject. Immense in its complexity, debilitating when the immune system malfunctions, our ability to fend off bacterial and viral infection, cancers of different types, and other foreign invaders is a remarkable biological capability. The NIH estimates 24M Americans are affected with an autoimmune disorder, but that […]
This week a remarkable paper was published in Nature, called “Accurate whole-genome sequencing and haplotyping from 10 to 20 human cells”. What makes it remarkable is the ability of this method to obtain rare variant phase information by changing the library preparation method. Until now to obtain completely phased individual […]
Although the whole genome versus whole exome discussion was held previously, details around the methods of selecting out the whole exome have been not discussed (also called ‘targeted selection’), and the wide array of methods, costs, and effort required can be a rather complicated affair.
