Gene Editing Activity with CRISPR/Cas9 Nickases and ssODNs.

Unsynchronized HCT116-19 cells were electroporated at a concentration of 5x105 cells/100ul with 2ug of the indicated CRISPR/Cas9 Nickase (1N, 2N, 3N, 4N, 5N) plus 1.35ug of 72NT. Following electroporation, cells were allowed to incubate for 48 hours. Correction efficiency was determined by the percentage of total viable eGFP+ cells in the population as described previously. Each treatment was performed in duplicate and error bars represent standard error.
