Surrogate reporter-based enrichment of cells containing RNA-guided Cas9 nuclease-induced mutations

RNA-guided endonucleases (RGENs), which are based on the clustered, regularly interspaced, short palindromic repeat (CRISPR)-CRISPR-associated (Cas) system, have recently emerged as a simple and efficient tool for genome editing. However, the activities of prepared RGENs are sometimes low, hampering the generation of cells containing RGEN-induced mutations. Here we report efficient methods to enrich cells containing RGEN-induced mutations by...
