Discovery Using Pooled Guide RNA LibrariesSystematically find phenotypes associated with genes or a combination of genes

Pooled DNA Oligo gRNA Libraries

Introduce guide cassettes into host cell

Select for phenotype

• A faster, more efficient method for functional screening libraries

• Genes identified by selection for phenotype and sequencing of gRNA

• gRNA / Cas9 expression maintained through selection process



CRISPR Pooled Functional Screening Library Workflow

Lentiviral Delivery Workflow• Viral delivery can efficiently introduce

CRISPR sequences into cells

• Requires integration for expression

• Can be titered to Multiplicity of Infection
