rAAV8-mediated CRISPR-SaCas9 introduction disrupted HBV DNA in the liver of HBV-Tg mice. (A) Assessment of off-target cutting by gRNA-Sa4. The results of the surveyor assay in liver cells treated with gRNA-empty (–) and gRNA-Sa4 (+) are shown; gRNA-Sa4 and gRNA-Sa4 off-target sites 1, 2, 3, 4, and 5 were PCR-amplified. T7EI nuclease-cleaved gRNA PCR products are indicated by Red arrow heads. (B) Representative views of target S4 region deletion in gRNA-S4-treated mice, generated using Integrative Genomics Viewer. Black bars: deletions; gray bars: sequencing reads.
