CRISPR/Cas9-mediated efficient and precise targeted integration of donor DNA harboring double cleavage sites in Xenopus tropicalis.

The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) 9 system has emerged as a powerful tool for knock-in of DNA fragments via donor plasmid and homology-independent DNA repair mechanism; however, conventional integration includes unnecessary plasmid backbone and may result in the unfaithful expression of the modified endogenous genes. Here, we report an efficient and precise CRISPR/Cas9-mediated integration strategy using a donor plasmid that harbors 2 of the same cleavage sites that flank the cassette at both sides. After the delivery of donor plasmid, together with Cas9 mRNA and guide RNA, into cells or fertilized eggs, concurrent cleavages at both sides of the exogenous cassette and the desired chromosomal site result in precise targeted integration without plasmid backbone.
