applicationEvaluation of the effectiveness of 10x Genomics assisted genome assembly
Currently, the human genomeThe successful case of de novo sequencing and assembly is the combination of Illumina short fragment sequencing, PacBio single-molecule real-time sequencing technology, and BioNano optical profiling technology, but PacBio's sequencing cost is relatively high in this method.
This study provides a genomeA new method for de novo sequencing and assembly. This method uses 10x Genomics linked reads to obtain medium to long fragment data, and then Illumina sequencing is used in combination with BioNano to construct a genome map. The contigs are anchored and scaffold, and the final assembled genome scaffold N50 reaches 33.5Mb. And the feasibility of this method was verified by genome de novo assembly of human HapMap sample (NA12878).
useThe results of genome assembly using the 10x Genomics+Illumina+BioNano method showed that both the scaffold N50 length and the assembled genome length were significantly increased, while the number of scaffolds was significantly reduced.
