Protocol
Activity Assay Protocol
Materials
Assay Buffer: 50 mM NaCl, 10 mM Tris-HCl, 10 mM MgCl2, 100 µg/mL BSA, pH 7.9
Recombinant S. pyogenes Cas9 NLS
DNA Substrate: PBR322 vector digested with EcoRISynthetic sgRNA, targeting sequence:, targeting sequence:GAGGCAGACAAGGTATAGGG
Ethidium Bromide, 10 mg/mL
Ultrapure DNase/RNase-Free Distilled Water, to prepare Assay Buffer
Assay
1. Prepare RNP Complex:
a. 600 nM sgRNA (6 µL addition from 3 µM stock prepared in Assay Buffer)
b. 0.25μg rSpCas9 NLS
c. Add Assay Buffer for a final RNP Complex volume of 26.5 µL
d. Incubate for 5 minutes at 37 °C.
2. Mix RNP Complex with 3.5 μL of 8.6 ng/µL of DNA Substrate (diluted in Assay Buffer, if possible).
3. Incubate for 1 hour at 37 °C.
4. Incubate for 10 minutes at 65 °C to dissociate enzyme from DNA.
5. Load total reaction with loading dye on a 1% agarose gel.
6. Run gel at 140 V for 40 minutes.
7. Soak gel in 200 mL TAE with 150 μL of 10 mg/mL ethidium bromide for 1 hour.
8. Use imaging software to detect and quantify hydrolysis of the DNA substrate.
