An FLT3-based assay providing further evidence that locating two nicks close together facilitates TPN-based targeted knock-in. (a) Experimental setup of targeted knock-in of an FLT3-ITD. The length of a homologous region in the donor plasmid (pcDNA/FLT3-ITD) is noted in parenthesis. ITD, internal tandem duplication. (b) The efficiencies of targeted knock-in of the 24-bp ITD in the K562 (left) and NALM-6 (right) cell lines determined by IDAA assays. IDAA, indel detection by amplicon analysis. Data represent mean and SEM values from three independent experiments.
