A NHEJ reconstitution system in which we can observe the joined products directly following PAGE would provide information on the ligation of each strand of the duplex, allow us to determine NHEJ efficiencies, and provide detailed mechanistic insight after sequencing the junctions (Fig. 1). One ear...
