Off-target analysis. (A) The target sequence and ten of the predicted off-target sites for sgRNA91/Cas9. The PAM sequence is labeled in blue. (B) A total of ten potential off target loci (Lanes 1–10) were selected to examine off target effects in EGFP site-specific knock-in cell clone. In order to further confirm the specificity of sgRNA91/Cas9, ten EGFP site-specific knock-in cell clones (EK1-EK10) were selected randomly were evaluated by PCR and sequencing. WT: Wild-type. (C) T7E1 assays for the ten potential off-target sites. OT1-OT10 represents 10 potential off-target sites, and T represents target site.
