"By incorporating Whole Genome Mapping, we were able to overcome the limitations of NGS' short read scaffolds to produce long super-scaffolds and finish the assembly to the near chromosome level," said Wen Wang, Deputy Director, Kunming Institute of Zoology, Chinese Academy of Sciences and an author of the paper. "We could not have completed the project without OpGen's technology."
In the study, OpGen's ARGUS system produced 100,000 single molecule restriction maps in three hours. This resulted in 30 times the physical coverage of the goat genome. The company's Genome Builder software generated long super-scaffolds by combining single molecule map data with sequence scaffolds generated by NGS and subsequent assembly. Specifically, the metric of assembly (N50) was improved eightfold by combining Whole Genome Mapping with NGS over NGS alone.
"While we continue to demonstrate the value of Whole Genome Mapping for assembly, quality control and validation of microbial genomes, we are pleased to expand its applications as a critical, complementary technology enabling investigators to provide complete and accurate long-range genomic information in complex, de novo projects," said Richard Moore, M.D., Ph.D., chief scientific officer of OpGen and an author of the paper. "This paper is the first of many we expect to be published over the next year which will validate OpGen's Whole Genome Mapping technology as a solution for the de novo assembly of the spectrum of genomes from microbes to mammals."
