Pooled CRISPR sgRNA screening
We currently have several genome-scale CRISPR sgRNA libraries available for pooled screening of human or mouse cells. Pooled screens rely on selection strategies that enable separation of cells according to their phenotypes. Effects of the sgRNAs are quantitated as fold enrichment or depletion in the population after selection, see figure below. Screen phenotypes can be based on cell proliferation, such as drug resistance, synthetic lethality or on other selectable features, such as fluorescent reporters or cell size. Of note, pooled screens can utilize complex experimental models that are not amenable to screening in multiwell format, including in vivo animal models.
