    摘要: The invention provides for a method of producing a mutant somatic human cell line of cells comprising a genomic mutation of interest (MOI) at a predefined genomic site of interest (GOI) in close proximity to a genomic target site, which comprises: a) providing a guide RNA (gRNA) comprising a tracrRNA in conjunction with crRNA including an oligonucleotide sequence that hybridizes with the target site; b) providing an RNA-guided endonuclease which catalyzes the DNA break at the target site upon hybridizing with the gRNA; c) introducing the gRNA into the cells in the presence of the endonuclease to obtain a repertoire of cells comprising a variety of genomic mutations at the target site; d) selecting a cell from said repertoire which comprises a MOI; wherein the cell is haploid for the genomic locus of the target site; and e) expanding the cell to obtain the mutant cell line. The invention further provides for a mutant human somatic cell line obtainable by such method; and libraries of mutant human somatic cell lines of isogenic cells with a variety of genomic mutations at different predefined genomic target sites.

    摘要: Provided is a kit or a system including two elements or components. The first component (i) is a selective component including a nucleic acid sequence and at least one proto-spacer. The second component (ii) includes at least one sensitizing component including at least one cas gene and at least one CRISPR array. At least one spacer of the CRISPR targets a proto-spacer included within a pathogenic gene of a bacterium so as to specifically inactivate said pathogenic gene in said bacterium and wherein at least one spacer of said CRISPR targets a proto-spacer included within said selective component of (i) so as to specifically inactivate said selective component. Further provided is a method using the components or kits of the invention for interference with a horizontal transfer of a pathogenic gene between bacteria and for preventing a pathologic condition in a mammalian subject caused by a bacterial infection.

    摘要: Provided are a novel two-step gene targeting method and a nucleotide construct for gene targeting. The method can improve the gene targeting efficiency and accurately identify a target gene knock-out mutant. The method of the present invention comprises: firstly, efficiently replacing a target gene in a genome with a targeting box by homologous recombination, the targeting box consisting of a target gene activity variant, a marker gene and site-specific recombination sites; and secondly, resecting the targeting box by recombinase, leaving a site-specific recombination site on the target gene to generate a target gene knock-out mutant, and removing a recombinase expression vector from the knock-out mutant by using a counter selection marker in the recombinase expression vector.
