Abstract
Abstract CRISPR/Cas9 gene knock-out technology can be used as a powerful tool for large-scale functional genomic analysis in mammalian cells. With the goal to establish a cost-effective functional genomics platform for the discovery of therapeutic targets, we developed a highly functional high throughput lentiviral gRNA/CRISPR screening platform, enabling scientists to perform pooled format genome-wide CRISPR/Cas9 genetic screens. Three 55K gRNA libraries were designed to cover the whole protein-encoding human genome with a redundancy of 8 gRNAs per gene. As supporting tools, we developed protocols, reagents, and software tools for hit validation and target prioritization. Here we show the results of parallel genetic screens in a pair of isogenic CML cell lines (CML-R and CML-P), where the performance of CRISPR/Cas9 and RNAi screening platforms was compared for each cell line.
