Application of CRISPR/Cas9 Pooled Screening for a Non-immediate Readout Model

Linking phenotypes to genetic components has been an essential part of novel drug discovery, and screening methods have been widely employed to achieve such a goal. Screens can be conducted in either pooled or arrayed formats. Although arrayed screenings provide a better and cheaper alternative in small scale, the larger-scale screenings are conducted in pooled manner. With its adaptability to various models and conditions, CRISPR/Cas9 technology provides an invaluable alternative to classical and RNAi-based screening methods. Combined with high-throughput sequencing and bioinformatics, CRISPR-/Cas9-based pooled screening methods provide unbiased and robust data. In this protocol, we employed CRISPR-/Cas9-based pooled screening for a non-binary and non-immediate readout.
