Cas9 Expressing Cell Lines

• Stable Cas9 integration
• Minimized need for co-transfection or co-transduction of sgRNAs
• Ideal for high-throughput sgRNA applications
• Consistent, high-level Cas9 expression in a uniform genetic background
• Cas9 functionally validated using the IndelCheck™ T7 Endonuclease I assay
• Compatible with GeneCopoeia Genome-CRISP™ sgRNA clones, sgRNA libraries, and donor clones

GeneCopoeia´s stable cell lines constitutively expressing the CRISPR Cas9 nuclease enable you to carry out CRISPR genome editing applications with high efficiency.

The Genome-CRISP™ Cas9 stable cell lines are available pre-made in many human, mouse, and rat cell line backgrounds. The CRISPR Cas9 nuclease is stably integrated into either the human AAVS1 or mouse ROSA26 “Safe Harbor” sites, or randomly via lentiviral-mediated transduction.

The CRISPR Cas9 nuclease, in combination with single guide RNAs (sgRNAs), is widely used to create targeted genomic modifications, from gene knockouts, mutagenesis, fusion tagging, and more, in eukaryotic cells and animal models. Stable Cas9 integration ensures robust and consistent expression of the CRISPR Cas9 nuclease.


• High-throughput knockout screening with many sgRNAs, either individually or in pools.
• Ideal for drug target discovery (Figure below).
• Convenient validation of several drug target candidates.
• Applications requiring inducible genome modification.
• Validation of sgRNA cleavage activity in a fast-growing, easy-to-transfect or transduce model cell line, either prior to transfection/transduction of your cell line, or to troubleshoot sgRNAs with little or no cleavage activity.

Example applications of Cas9-expressing stable cell lines
Use of the GeneHero™ Cas9 stable cell lines with CRISPR sgRNA libraries for drug target discovery.

A. Pooled screen. Cas9-expressing cells infected with each sgRNA library pool are screened for the desired readout. Pooled cells are subjected to Sanger sequencing for individual sgRNAs, or deep sequencing to look for over- or under-representation of individual sgRNAs.

B. Knockout screen using arrayed sgRNAs. Cas9-expressing cells are infected with individual sgRNA lentiviruses. Wells are screened for the readout of interest. Individual sgRNAs corresponding to the phenotype of interest are already known without sequencing.
