BioNano Genomics announced the purchase of an Irys System by BGI, the world’s largest genomics organization. BGI selected BioNano’s platform to enable comprehensive exploration of human structural variation (SV) and to provide vastly improved assemblies for various organisms of interest, including those where no reference exists. In addition, BioNano and BGI will partner together to develop new methods for multiplexing on the Irys System, enabling significantly higher sample throughput to be performed with fewer reagents, a capability that will be particularly useful for large-scale studies.“We have been collaborating with BioNano Genomics on human samples of Asian descent and are impressed by the capabilities of the Irys technology to efficiently detect hundreds of large (>1kb) complex genomic structural variations,” said Xun Xu, deputy director at BGI. “As part of our efforts to further elucidate genome biology, BGI needed a solution to investigate large structural variation that is not easily accessible through sequencing, DNA arrays or other technologies. Now it is feasible to do population-scale, comprehensive large structural variation discovery on a single technology platform using BioNano’s Irys System.”
The Irys System, which is based on the high-throughput chip, IrysChip V2, is an ideal SV discovery tool because it can detect all types of SVs in a single run, enabling rapid and accurate de novo genome assembly and genome completion. Genome maps built with the Irys System reveal the biologically and clinically significant order and orientation of functionally relevant components of complex genomes, including genes, promoters, regulatory elements, the length and location of long areas of repeats as well as viral integration sites across the entire genome that are often implicated in the cause of complex diseases such as cancer. Assembling such a comprehensive view of a genome has previously been a major hurdle because information about large repetitive elements and structural variations are lost with next generation sequencing (NGS) methods.
“We are very excited to add this platform to our portfolio of cutting edge technologies and service solutions as we seek to continue providing better and more comprehensive genomic services for our customers worldwide,” said Yingrui Li, CEO of BGI Tech, a subsidiary of BGI that provides scientific and technological service solutions to biomedical, agricultural, and environmental customers globally.
“With the Irys System, we enable researchers to rapidly identify accurate structural information over long-range distances with virtually no alteration to the native genomic samples,” said Han Cao, founder and chief scientific officer of BioNano Genomics. “As a versatile and sensitive single molecule imaging platform, Irys enables the de novo assembly of genomes containing complex, highly variable regions, as well as the accurate detection of all types of structural variation, both balanced and imbalanced, within complex heterogeneous samples.”
BGI is the latest to adopt the Irys System. Others include the Garvan Institute, who are using their Irys for human and cancer genomics, UC San Francisco, for genomic investigations of a range of species from viruses to humans, and Kansas State University, for the i5k Insect and other Arthropod Genome Sequencing Initiative.
