Supplementary Figure 5: Confirmation of IDLV mapped off-target sites with the Surveyor assay.

HEK293T cells were transfected with the expression plasmids for Cas9 and (a) WAS CR-4, (b) WAS CR-5, (c) TAT CR-1. Cells transfected with the expression plasmids for Cas9 and GFP genes served as the negative control. Genomic DNA isolated 48 h later was subjected to the Surveyor assay (n=3), and percent of indel formation was determined. Results from duplicated transfection are shown. Arrows indicate the positions of the expected fragments. The gene near the CRISPR/Cas9 cleavage site is indicated on top of each gel. UD, undetectable.
