In this preprint, the authors propose a method for screening for off off-target CRISPR/Cas9 sites using PacBio and Oxford Nanopore sequencing. The amplification-free method purifies and sequences both on-target and off-target cut sites from a DNA sample. The method could prove useful for improving gRNA design and screening and suggests the ability to develop de Novo guides as opposed to requiring a reference genome. SageELF was used to fractionate (1-18KB) SMRTBells for PacBio Hi-Fi circular consensus sequencing.
