The less than $1000 cost is about 3 to 4 times less than what Illumina customers were experiencing in 2013. Many companies were claiming far prices at or near $1000 but those might not have being reading as thoroughly.
Building on the proven performance of Illumina SBS technology, HiSeq X Ten utilizes a number of advanced design features to generate massive throughput. Patterned flow cells, which contain billions of nanowells at fixed locations, combined with a new clustering chemistry deliver a significant increase in data density (6 billion clusters per run). Using state-of-the art optics and faster chemistry, HiSeq X Ten can process sequencing flow cells more quickly than ever before – generating a 10x increase in daily throughput when compared to current HiSeq® 2500 performance.
The HiSeq X Ten is sold as a set of 10 or more ultra-high throughput sequencing systems, each generating up to 1.8 terabases (Tb) of sequencing data in less than three days or up to 600 gigabases (Gb) per day, per system, providing the throughput to sequence tens of thousands of high-quality, high-coverage genomes per year.
The HiSeq X™ Ten, composed of 10 HiSeq X Systems, is the first sequencing platform that breaks the $1000 barrier for a 30x human genome. The HiSeq X Ten System is ideal for population-scale projects focused on the discovery of genotypic variation to understand and improve human health. (Photo: Business Wire)
Illumina announced the immediate availability of a transformative addition to its industry-leading next-generation sequencing portfolio with the launch of the NextSeq 500 System. The new sequencer packs high-throughput performance into an affordable desktop form factor, enabling researchers to perform the most popular sequencing applications in less than a day. The NextSeq 500 System is priced at $250,000.
Cost per genome to sequence up to April 2013
Who are the main contenders in the race to less than $100 genome sequencing ?
Dozens of startups are trying to carve off their chunk of a genetic testing market that UnitedHealthcare estimates could reach $25 billion annually by 2021.
Innovations like "ion torrent" sequencing, created by a startup acquired in 2010 by Life Technologies, aim to slash costs. Sequencing has traditionally been done optically, by flooding DNA snippets with chemicals called reagents that contain one of DNA's four bases. Every base has only one match; when a base finds a match, a light flashes. The sequencer sees it and records the base.
With the Ion Proton System -- a $100,000 machine that can sit on top of a table -- it's not light that's being recorded, but changes in pH balance. The DNA snippets being sequenced are attached to tiny beads sitting in as many as a billion tiny wells on a custom-designed semiconductor chip. The chip is flooded with DNA nucleotides, and when a base snaps into place, a hydrogen ion is released and recorded.
Eric Topol, a professor of genomics and director of the Scripps Translational Science Institute in San Diego, says chip sequencing -- without expensive reagents -- has the potential to be "remarkably cheaper" than traditional optical sequencing.
Illumina's arrays are quickly becoming cheaper and denser. Other advances are also driving down prices.
Topol cites innovations like nanopore sequencing, which passes DNA through a protein nanopore: "That's a very efficient way of getting millions and millions of bases read." That approach still has "significant problems with accuracy," he noted.
Oxford Nanopore is a leader in nanopore sequencing.
Government grants focus on nanopore sequencing
The use of nanopore technology aimed at more accurate and efficient DNA sequencing is the main focus of grants awarded by the National Institutes of Health. The grants – nearly $17 million to eight research teams – are the latest awarded through the National Human Genome Research Institute (NHGRI)'s Advanced DNA Sequencing Technology program, which was launched in 2004. NHGRI is part of NIH.
"Nanopore technology shows great promise, but it is still a new area of science. We have much to learn about how nanopores can work effectively as a DNA sequencing technology, which is why five of the program's eight grants are exploring this approach," said Jeffery A. Schloss, Ph.D., program director for NHGRI's Advanced DNA Sequencing Technology program and director of the Division of Genome Sciences.
Nanopore-based DNA sequencing involves threading single DNA strands through tiny pores. Individual base pairs – the chemical letters of DNA – are then read one at a time as they pass through the nanopore. The bases are identified by measuring the difference in their effect on current flowing through the pore. For perspective, a human hair is 100,000 nanometers in diameter; a strand of DNA is only 2 nanometers in diameter. Nanopores used in DNA sequencing are 1 to 2 nanometers in diameter.
This technology offers many potential advantages over current DNA sequencing methods, said Dr. Schloss. Such advantages include real-time sequencing of single DNA molecules at low cost and the ability for the same molecule to be reassessed over and over again. Current systems involve isolating DNA and chemically labeling and copying it. DNA has to be broken up, and small segments are sequenced many times. Only the first step of isolating the DNA would be necessary with nanopore technology.
Innovation is crucial in these as well as the other (non-nanopore) studies being funded. For example, one research team eventually hopes to use light to sequence DNA on a cell phone camera chip for under $100.
