De novo sequencing refers to sequencing a novel genome where there is no reference sequence available for alignment. Sequence reads are assembled as contigs, and the coverage quality of de novo sequence data depends on the size and continuity of the contigs (ie, the number of gaps in the data).
Next-generation sequencing (NGS) enables faster, more accurate characterization of any species compared to traditional methods, such as Sanger sequencing. Illumina offers mate pair sequencing and long-read technology to complement shorter reads for comprehensive, accurate characterization of any species.
Assemble novel bacterial genomes with this simple workflow solution.
When sequencing a genome for the first time, use a combined approach for higher-quality assemblies. Combining short-insert, paired-end and long-insert, mate pair sequences is the ideal way to maximize coverage. The short reads, sequenced at higher depths, can fill in gaps not covered by the long inserts.
This combination enables detection of the widest range of structural variant types and is essential for accurate identification of complex rearrangements. Synthetic long reads can also aid assembly by providing long contigs that are “stitched” together from shorter reads to maintain accuracy.
