Abstract
Prime editing introduces single-nucleotide polymorphism changes, small deletions, or insertions at a specific genome site without double-stranded DNA breaks or the need for the donor template. Here, we present a protocol to design, conduct, and evaluate prime editing in human pluripotent stem cells. We describe steps for pegRNA and nicking sgRNA design and cloning, the prime editing tool electroporation, and the efficiency evaluation using Miseq. We elaborate the process of GBA (N370S) mutation induction and correction as an example. For complete details on the use and execution of this protocol, please refer to Li et al. (2022).1.
