CRISPR screen to determine host factors

Discover host factors critical for SARS-CoV-2 pathogenesis and identify novel therapeutic targets

CRISPR screens in the field of virology are ideally suited for analyzing virus-host interactions; determining host factors critical for virus entry, replication, and spread; and identifying and prioritizing novel drug targets. Performing a genome-scale CRISPR/Cas9 knockout screen with an sgRNA library can help identify important host factors responsible for disease response.

The Guide-it CRISPR Genome-Wide sgRNA Library System is a pooled lentiviral sgRNA library for performing phenotypic knockout screens in human cell lines. The system is based on the Brunello library (Doench et al. 2016; Doench et al. 2018), and contains over 76,000 guide RNAs (sgRNAs) targeting about 19,000 genes, with four highly active guides per gene, as well as nontargeting sgRNA controls. The amplified, validated library is provided as a ready-to-use lyophilized transfection mix enabling easy production of high-titer lentivirus and setup of genome-wide CRISPR screens (Figure 1).

Following screening, next-generation sequencing (NGS) analysis can be performed to identify candidate genes of interest using the Guide-it CRISPR Genome-Wide sgRNA Library NGS Analysis Kit, which includes the necessary primers and reagents to prepare Illumina-sequencing-ready NGS libraries from cell populations transduced with our genome-wide sgRNA library.

Quality control to ensure sgRNA representation

Our library has been carefully manufactured to ensure proper sgRNA representation. We have measured sgRNA representation at every step in the process: library synthesis, amplification, viral production, and target cell transduction (Figure 2).

The Guide-it CRISPR Genome-Wide sgRNA Library System includes all of the components necessary to perform five lentiviral-based, genome-wide CRISPR/Cas9 knockout screens in human cells. Provided with the kit are lentiviral vectors for expression of Cas9 and >76,000 sgRNAs targeting >19,000 human genes (four guides per gene) in lyophilized, ready-to-transfect formats that simplify the production of high-titer lentivirus. The sgRNA library included with this kit is based on the Brunello library (Doench et al. 2016), and incorporates design features intended to maximize on-target efficacy and minimize off-target effects. To ensure balanced guide representation, we analyze the sgRNA library by NGS to confirm that >90% of the included sgRNAs fall within a 10-fold distribution range. Enrichment or depletion of sgRNAs in screened cells can be analyzed by NGS with the Guide-it CRISPR Genome-Wide sgRNA Library NGS Analysis Kit (Cat. # 632647).
