Whole-genome, High Resolution Maps to Complement Sequence Assembly

The increased use of next generation sequencing has led to the generation of many genome assemblies; however, they are often incomplete and not contiguous. While long-read technologies have improved assembly contiguity, they are more expensive and still lack sufficient read length to resolve complex structures. Optical mapping technologies have been used to scaffold and improve assemblies, but the inherent limitation on resolution and precision limits utility, especially in combination with short-read data. To provide the necessary long-range information while maintaining sufficient resolution to complement next generation sequencing technologies, Nabsys has developed its HD-Mapping™ platform to construct electronic whole genome maps. By analyzing reads that are hundreds of kilobases in length, electronic detection preserves long-range information while simultaneously achieving better than 300 bp single molecule resolution.
