Figure Lengend Snippet: Fig. 2 The modified 3TC scaffold boosts SpCas9 gRNA expression levels compared to the original 4T scaffold. (A) DNA sequence of the 4T and modified 3TC scaffolds. (B) Relative quantification (RQ) of mDmd gRNA delivered by nucleofection of PX459.V2 (4T) to C2C12 cells, by qRT-PCR. Mean Log2RQ ± 95% CI; n = 3. One-way ANOVA with Dunnett’s multiple comparisons test was performed on ΔΔCT values, **p ≤ 0.01, ***p ≤ 0.001. (C, D, E) Comparison of the relative quantities of mDmd Sp gRNA, delivered by PX459.V2, pdg459.V2 (2 × 4T) and PX459.V3 (3TC), measured by qRT-PCR. Mean Log2RQ ± 95% CI; n = 3. One-way ANOVA with Tukey’s multiple comparisons test performed on ΔΔCT values, **p ≤ 0.01, ***p ≤ 0.001

Article Snippet: SaCas9Puro.V2 was generated by replacing the SpCas9 coding sequences of PX459.V2 with SaCas9 coding sequences from PX601 (Addgene #61591).

Figure Lengend Snippet: Fig. 5 Editing efficiencies of high-fidelity SpCas9s with the 3TC scaffold. Comparison of PX459.V2 SpCas9-HF1 (4T), PX459.V3 SpCas9-HF1 (3TC), PX459.V2 eSpCas9(1.1) (4T) and PX459.V3 eSpCas9(1.1) (3TC) plasmids de livered by lipofection at a (A) high and (B) low plasmid dose without puro mycin selection in HEK239T cells, assessed by deep amplicon sequencing. Mean ± SEM; n = 3. Two-way ANOVA with Šídák’s multiple comparisons test; *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001. (C) Editing efficiencies of hDMD-B in the G19 gRNA configuration with WT and high-fidelity Sp-Cas9 plasmids delivered by nucleofection with puromycin selection in HEK293Ts. Two- way ANOVA with Šídák’s multiple comparisons test; *p ≤ 0.05, ***p ≤ 0.001
