WebAug 3, 2024 · The Csy4 construct containing two LOB1 gRNAs achieved the successful editing of LOB1-gRNA1m-eGFP and LOB1-gRNA2m-eGFP, as indicated by green fluorescence (Supplementary Fig. 7). We then used the same gRNAs used in tRNA-based multiplex genome editing for CsPDS in Csy4 constructs (Fig. 5 a). WebAug 4, 2015 · Using the Csy4-gRNA template, we obtained pre-RNAs for all selected sites and produced the corresponding gRNAs by incubation with Csy4 protein. For the EGFP, we injected Cas9/gRNA into the tg...
Development of a Csy4-processed guide RNA delivery system …
WebMar 2, 2015 · The only proven method based on such a strategy is the expression of Csy4 endoribonuclease (endo-RNase) with Cas9 to process a transcript containing gRNAs fused with Csy4-cleavable RNA (12, 13). … WebSep 13, 2024 · Results: To develop a ALSV-based gRNA delivery system, the Cas9-based Csy4-processed ALSV Carry (CCAC) system was developed. In this system, we engineered the soybean-infecting ALSV to carry and deliver gRNA (s). The endoribonuclease Csy4 effectively releases gRNAs that function efficiently in Cas9-mediated genome editing. iron lion customs
Expansion of CRISPR/Cas9 genome targeting sites in zebrafish by Csy4 ...
WebApr 25, 2014 · In Csy4 optimization experiments, 500 ng of pCAG-Csy4-T2A-Cas9 (pSQT834) and 250 ng of gRNA encoding plasmids were transfected with 50 ng of ptdTomato-N1 expression plasmid (Clontech) as a ... WebDec 24, 2024 · For STU-Cas9-Csy4, a P2A ribosomal skipping peptide (Szymczak et al., 2004) was used to translate Csy4 and Cas9 from a single transcript (Figure 1a). With these four Cas9 systems, we targeted six sites in the rice genome. The resulting 24 constructs were used for transient transformation of rice protoplasts. WebCurrent CRISPR-Cas9 multiplexing strategies. (A) Csy4, ribozyme, and tRNA-based configuration.
