We found BE﹎ediated gene knockout yielded fewer genotypes. BE﹎ediated gene editing precisely achieved silencing of two neighbouring genes, while CRISPR/Cas9 may delete the large fragment between two target sites. WebJul 2, 2024 · Adenine base editors (ABEs) catalyze A-to-G conversions at genomic sites of interest. However ABEs also induce cytidine deamination. We engineered ABEs to reduce the cytosine editing activity of them. This behind the paper post covers our recent work on development of more precise base editors. sonic-generations
