De novo sequencing refers to the sequencing of a novel genome without a reference sequence for alignment. The process of de novo genome sequencing involves the sequencing of DNA fragments, assembling the reads into longer sequences (contigs) and finally ordering the contigs to obtain the entire genome sequence.
BGI is a recognized leader in de novo Whole Genome Sequencing and has extensive experience from the de novo sequencing and published more than 400 species’ genomes. Currently, more than 1000 plant and animal genomes have been sequenced by BGI and its partners (including unpublished species)
We offer a complete suite of technologies to support your de novo sequencing projects, along with expert assistance with the planning of optimal sequencing and bioinformatics options, to assure your project is a success.
We care for your samples from receipt through to result reporting. Highly experienced laboratory professionals follow strict quality procedures to ensure the integrity of your results.
