Title:
METHOD FOR PRODUCING KNOCK-IN CELL
Document Type and Number:
WIPO Patent Application WO/2020/204159
Kind Code:
A1
Abstract:
It was found out that, by using a site-specific nuclease system which comprises a combination of a molecule simultaneously targeting and cleaving one homology arm sequence of a donor DNA and a genome sequence corresponding to the homology arm sequence, and a molecule targeting and cleaving a genome region close to the site to be cleaved by the aforesaid molecule, reparation via both of non-homologous end joining and homologous recombination is induced between the genome DNA and the donor DNA, and thus a cell, an organism, etc. in which a long-chain donor sequence is knocked-in can be produced at high efficiency and high accuracy.
