Nettet12. apr. 2024 · Base editing, first reported in 2016, is capable of installing C•G to T•A and A•T to G•C point mutations, while largely circumventing some of the pitfalls of traditional CRISPR/Cas9 gene editing. Despite their youth, these technologies have been widely used by both academic labs and therapeutics-based companies.

Nettet12. sep. 2016 · The intein–Cas9 enzyme was PCR amplified from pKMD111e-intein–Cas9(S219-G521R), which was a gift from D. Liu (Addgene plasmid 64192), …
Nettet9. okt. 2024 · Using a plant-based biosensor, we demonstrated for the first time that the split-SpnCas9 is capable of inducing efficient base editing in plant cells and identified several valid split sites for future biodesign strategies. Overall, this strategy provides new opportunities to bridge different CRISPR/Cas9 tools including base editor, prime ... NettetCRISPR-Cas9 genome editing can be spatially and temporally regulated with a variety of genetic, small molecule, and optical techniques. Intein-Cas9 and iCas can be regulated with the small molecule 4-hydroxytamoxinfen (4-HT). Whereas 4-HT-induced intein splicing renders Intein-Cas9 constitutively active, iCas is bidirectionally regulable.
