KeyGene reference: P232


The invented methodology is a combination of TarSeq and subsequent selective sequencing, which results in a highly effective method for target sequence enrichment. TarSeq is a CRISPR-based technology selectively isolating and targeting regions of interest and protecting them from exonuclease treatment, thereby allowing for PCR-free enrichment. Subsequently applying selective nanopore sequencing makes sure an optimal enrichment of target sequences is obtained.


The technology is highly flexible with regard to target sequence length (e.g. 1-20 Kb) as well as the number of targets to be enriched. Moreover, the technology is PCR-free, allowing for comprehensive variation detection of single nucleotide polymorphisms (SNPs), structural variations (SVs) and base modification (e.g. C methylation). Moreover, it is not biased by preferential amplification of for instance specific alleles.


In research and fields like crop breeding, there is a high demand for a technology that can enrich important genomic loci of samples to be selectively sequenced in a cost-effective way without PCR bias. KeyGene’s targeted sequencing technology is specifically linked to long-read sequencing and therefore highly instrumental in elucidating complex genomic structures, like copy number variation, larger insertions, and deletions, and inversions.
