WebRecombinant dCas9 (D10A & H840A) protein in solution is temperature sensitive and must been stored at -20°C or below to prevent degradation. Avoid repeated freeze /thaw cycles and keep on ice when not in storage. … WebThe third variant is a nuclease-deficient Cas9 (dCas9, Figure 2C) (21). Mutations H840A in the HNH domain and D10A in the RuvC domain inactivate cleavage activity, but do not prevent DNA binding (11, 22). …

We’ll use SpCas9 nickases as examples for this post. The D10A mutation inactivates the RuvC domain, so this nickase cleaves only … See more The potential benefit of using nickases for HDR is targeting range: using an individual gRNA with WT Cas9, repair levels decrease rapidly 10 bp from the cut site. So if you can’t find a good gRNA that cuts close to your … See more Ready to employ nickases for your next CRISPR experiments? Here’s IDT’s best advice: 1. Use a PAM-out configuration 1. Optimize your spacing 1.1.
