Article Title: Mechanism of Cas9 inhibition by AcrIIA11
doi: 10.1093/nar/gkaf318
Figure Lengend Snippet: AcrIIA11 inhibits SaCas9 in vitro and in human HEK293T cells. ( A ) Agarose gel and ( B ) quantification of DNA cleavage by SaCas9. Graphs represent the mean of three replicates. Error bars: S.E.M. ( C ) HEK293Ts are transiently transfected with plasmids carrying SaCas9 + sgRNA. A second plasmid encodes either AcrIIA4 (positive control) or AcrIIA11. ( D ) Representative agarose gel and ( E ) quantification of indel percentage for the CACNA1D site. Error bars are the standard deviation of three replicates. P -values (not significant [ns], P > 0.05; *** P < 0.001; **** P < 0.0001) were determined using a Student’s t -test. ( F ) Quantification of the editing efficiency when AcrIIA11 or AcrIIA4 are present relative to when no Acr is expressed. Error bars are the standard deviation of three replicates. P -values (not significant [ns], P > 0.05; **** P < 0.0001) were determined using a Student’s t -test.
Article Snippet: The Sa Cas9 and CMV promoter-driven AcrIIA4 expression vectors were purchased from Addgene (Plasmid #85452 and #113038) [ , ].
