In 2014, genomic sequencing large, Illumina, introduced that their new machine might sequence entire human genomes for $1,000 per genome. It was a major milestone for a know-how that had price some $95 million per genome when it arrived early this century.
Illumina now dominates the business; however this week, we discovered it has some critical new competitors. Ultima, a five-year-old firm that’s been working in stealth, mentioned its sequencing know-how can piece collectively entire genomes at $100 per genome. Ultima additionally introduced it has raised $600 million from a number of enterprise capital companies—together with Andreessen Horowitz, Founders Fund, and Khosla Ventures—to go even decrease.
“We basically enabled studying much more DNA on the identical time,” Gilad Almogy, Ultima’s founder and CEO, instructed Bloomberg. “A $100 genome is a serious inflection level but it surely’s undoubtedly not the top of the highway. There’s a long time forward of us. We’ve to maintain pushing.”
The announcement’s timing is not any coincidence. The business’s greatest convention, Advances in Genome Biology and Know-how (AGBT), takes place subsequent week, and Ultima plans to make a splash. Along with pulling again the veil on its work and monetary backing, the startup additionally launched 4 papers detailing the know-how, alongside info on bioinformatics and AI partnerships with Google DeepVariant and Sentieon.
“Ultima is the true deal, with good know-how,” Raymond McCauley, cofounder and chief architect at BioCurious and chair of digital biology at Singularity Group, instructed Singularity Hub. “They’ve been engaged on an Illumina killer for years.”
The $100 Genome
To sequence a genome, scientists first should shatter it. Subsequent-generation sequencing applied sciences break genomes into fragments of some hundred nucleotides—the molecular letters A, G, C, T—and scatter them throughout a floor with billions of microscopic wells etched into it. A sequence of chemical reactions amplify and put together the DNA, then sequences from every effectively are recorded (normally optically) and pieced again collectively.
This strategy has repeatedly slashed the price of sequencing through the years, however lately, the pattern has slowed. To interrupt the bottleneck, Ultima says their gene sequencing machine, the UG 100, exploits the very best components of the method whereas enhancing on just a few key factors.
For sequencing, Ultima makes use of a disc that’s a little bit larger than a CD. The disc’s floor is peppered with 10 billion “touchdown pads” to draw brief DNA sequences. They spin up the disc to uniformly disperse reagents throughout its floor after which, like in a CD participant, optically learn the DNA snippets trapped in every touchdown pad. Lastly, their system items the brief sequences again along with a machine studying algorithm.
It’s not an entire reinvention of the method. Moderately, Ultima’s system finds plenty of “intelligent methods to save lots of prices and add efficiency,” in accordance with McCauley. These embrace extra effectively utilizing reagents—a giant contributor to prices—with their spinning, open-flow-cell design and involving AI early. Altogether, the financial savings add as much as a system that seems to be as correct because the competitors however is dramatically extra cost-efficient.
“It seems to be like they’ll ship an actual $100 genome, in the event you take a look at price of consumables—reagents, the specialised chemical compounds and organic elements of the flamboyant reactions that occur to drive DNA sequencing on the machine,” mentioned McCauley, who was additionally a member of the staff that developed Illumina’s next-generation DNA sequencing tech.
In response to the Nationwide Human Genome Analysis Institute, the price to sequence an entire human genome was $562 as of final 12 months. Ultima’s claimed $100 genome would cut back the fee by 82%. Notably, Almogy says they’ll go decrease, and buyers appear to agree.
However the price of the machine itself is an open query that might decide the tempo of adoption, in accordance with McCauley.
Will researchers should pony up one million {dollars} to get $100 genomes? It’s additionally unsure how rapidly analysis teams might swap machines, he mentioned. They might not wish to make adjustments midstream. Not solely may it require a giant sunk price, however “evaluating Ultima apples to Illumina oranges” may really feel dangerous. On the identical time, 10 occasions as many genomes for a similar quantity of grant cash might show alluring.
In both case, Illumina might really feel compelled to decrease costs to compete. “Even when that is all that occurs, it’s going to shake up the business and be a giant step ahead,” McCauley mentioned.
Goals and Actuality
The utility of genomic sequencing received a real-world take a look at in 2020. When the pandemic hit, scientists sequenced the genome of SARS-CoV-2 and blasted it to colleagues world wide. The makers of mRNA vaccines used the sequence to develop viable vaccine candidates in a matter of days. These candidates later turned two of the authorized vaccines which have saved an estimated 2.2 million lives during the last 12 months and a half.
Additional driving down the price of sequencing human genomes might even have wide-ranging results, from improved most cancers care to extra absolutely decoding life’s supply code. The dream is to make entire genome sequencing a medical no-brainer, and by evaluating genomes throughout entire populations, scientists hope to additional tease out which genes do what.
However after we’ll understand that dream continues to be unsure. “Will this decrease the value of DNA sequencing sufficient to be a part of a go to to your physician’s workplace to find out what specific micro organism you’ve received or see your most cancers threat? That reply will emerge extra slowly, and rely upon regulatory approval of the brand new platform,” McCauley mentioned.
Additionally, with all promising new applied sciences, it’s good to recollect: Biology’s complexity by no means hesitates to humble expectations. Nonetheless, as scientists proceed to unwind life’s twisted story, if we are able to scale back the price of studying from hardback to paperback, all the higher.
