[PMC free article] [PubMed] [Google Scholar] 26. has been the most highly used CRISPR system and its use for genome editing only requires the presence of the Cas9 nuclease and a guide RNA (gRNA). In concern for translation of this methodology to clinical trials. While several groups have described novel mutant Rabbit Polyclonal to ADCK5 Cas9 enzymes with reduced off-target cleavage activity26C28, these experiments were performed with plasmid-based Cas9 delivery several groups have described novel mutant Cas9 enzymes with reduced off-target cleavage activity26C28, these experiments were performed with plasmid-based Cas9 delivery systems in immortalized cell lines, as opposed to RNP delivery. Therefore, discovery of a Cas9 mutant that does not sacrifice on-target activity while reducing OTEs in the RNP context would have great impact on therapeutic genome editing. Using an unbiased bacterial screening approach, we identified a single point mutation (R691A) in Cas9 (hereafter referred to as high fidelity Cas9,…
