  • Title: Simplified CRISPR-Mediated DNA Editing in Multicellular Eukaryotes.
    Author: Kumar R, Tiwari K, Saudagar P.
    Journal: Methods Mol Biol; 2023; 2575():241-260. PubMed ID: 36301478.
    Abstract:
    The CRISPR-Cas9 system is becoming an imperative tool to edit the genome of various organisms. The gene-editing study by the CRISPR-Cas9 system has revolutionized the diverse field of biomedical research, genome engineering, and gene therapy. CRISPR-Cas9 system has been modified to induce genome editing by small-guide RNAs, which function together with Cas9 nuclease for sequence-specific cleavage of target sequences. Here, we describe the simplified protocol of CRISPR-Cas9-mediated DNA editing in multicellular eukaryotes, including the construction of gRNA plasmids into vectors, screening of positive clones, transfections into 293FT cell line, and transduction into Jurkat cells. We also describe different bioinformatic tools to design suitable gRNAs with increased efficiency and decreased off-target events. Further, we describe the assessments of DNA editing by indel mutations and sequencing in transduced cells.
