A-T to G-C base editing efficiency at targeted gene sites in HEK293T cell line

ABSTRACT: A-T to G-C base editing efficiency at targeted gene sites in HEK293T cells using the dCas12f-ABE design or the Cas12f-ABE design. Found that the total A-T to G-C conversion efficiency of Circular gRNAs exhibited about two-fold increase compared with U6 gRNAs. We further analyzed the pattern for A-T to G-C conversion on the target site, and observed that the most efficient base editing occurred in a narrow window A3 (3bp downstream of the PAM) similar to U6 gRNAs. In summary, Circular gRNAs with dCas12f-ABE design could enhance A-T to G-C base editing efficiency in a narrow window.
