Genome-wide optical maps can be constructed using restriction enzymes to cut at specific sites along the DNA of organisms. These optical maps are unique DNA fingerprints that can be obtained from single DNA molecules.
Using BioNano Optical Mapping and Data Solution services, you can obtain the most complete genome assemblies and identify large-scale structural variations.
The BioNano Irys Instrument reveals genome structure by performing low-cost next-generation mapping at single-molecule resolution. Irys provides the long-range genomic information required for high-quality de novo assembly and high-resolution discovery of structural variations.
The BioNano Saphyr Instrument is a structural variation discovery platform. Saphyr detects structural variations (insertions, deletions, translocations etc.) ranging from 1,000 bp to megabase pairs in length using assembly and discovery algorithms.
You can use these next-generation mapping tools along with next-generation sequencing, especially for building reference genomes. Using the Irys System, researchers have assembled reference genomes for hummingbirds and the duck-billed platypus and have been able to increase the reference genome diversity in humans.
Another important application of physical genome mapping is to detect structural variations. This is due to the fact that unlike short-read sequencing technologies, optical genome mapping is not limited by size and can look at much larger and more complex regions to identify variants. Thus, whole-genome optical mapping can be a useful complementary tool to NGS for observing large complex rearrangements and structural variations.
