Supplementary Figure 10: Base-skipping CRISPR mutants mediate efficient on-target cleavage.

HEK293T cells were transfected with the Cas9 expression plasmids with (a) WAS CR-4 and (b) WAS CR-5 as indicated, and the genomic DNA harvested 48 h later was assessed using the Surveyor assay (n=3). Efficient target cleavage was observed in some mutants with one-base skipping. Arrows indicate the positions of the expected fragments. UD, undetectable.
