Extended Data Fig. 9. PE7 enhances prime editing in different cell lines and with different edit types with minimal effect on off-target editing.

Extended Data Fig. 9

a, Percentages of prime editing outcomes at DNMT1 and VEGFA loci in HEK293T, HeLa, and U2OS cells. b, Percentages of prime editing outcomes at HEK3 locus in HEK293T cells. c, Fold changes in intended prime editing. Editing percentages in Fig. 4c. d, Percentages of editing outcomes produced by PEmax or PE7 with the PE2 approach at on- and off-target sites using pegRNAs targeting the EMX1 (top left), HEK4 (top right), FANCF (bottom left), and HEK3 (bottom right) loci in U2OS cells. On-target editing data also presented in Fig. 4c and Extended Data Fig. 11a. Editing components delivered by plasmid transfection in a-d. Data and error bars in a, b and d indicate mean ± s.d. (n = 3 independent biological replicates). Horizontal bars in c indicate medians (8 edits) of ratios of means (n = 3 independent biological replicates for each edit). P-values in d are from two-tailed unpaired Student’s t-test.
