DEUX-seq™

Nomination assay

SeQure's DEUX-seq is a biochemical, orthogonal nomination assay that validates and reinforces ONE-seq findings to support regulatory requirements. DEUX-seq leverages in vitro cutting of genomic DNA followed by deep sequencing to determine potential off-target effects with your gene editing tool of interest.

ONE-seq for Variant-Aware Therapeutic Guide Selection
Shown here in a line graph are cumulative counts of candidate off-target loci based on their ONE-seq scores. All loci with assigned ONE-seq scores are represented here. As ONE-seq score increases, number of off-target loci decreases dramatically, indicating that majority of sites do not show clear evidence for cleavage in the ONE-seq assay.
