Generation of an external guide sequence library for a reverse genetic screen in Caenorhabditis elegans.

abstract：BACKGROUND:The CRISPR/Cas9 genome editing system has greatly facilitated and expanded our capacity to engineer mammalian genomes, including targeted gene knock-outs. However, the phenotyping of the knock-out effect requires a high DNA editing efficiency. RESULTS:Here, we report a user-friendly strategy based on the ex...
