Figure 2. In vitro digestion of candidate guideRNAs to test cutting efficiency.

Figure 2.

Target DNA was digested for 20 min at 37 °C with a cocktail consisting of crRNA, tracrRNA, and Cas9 enzyme. Digestion products were run on a gel and cutting efficiency was assessed based on the resulting bands. Uncut amplicons (white arrows) show a band at 400 bp and the digested products (blue arrows) show a band at 200 bp.
