    CRISPR-Cas9 Screening Libraries

    Pooled sgRNA or arrayed crRNA for high-throughput gene editing studies

    Investigation of entire gene families or biological pathways is enabled by our broad suite of custom and pre-defined libraries of CRISPR-Cas9 reagents. Both pooled and arrayed screens can take advantage of our algorithm-optimized guide RNA designs for high functionality and superior specificity.


    The Dharmacon Edit-R CRISPR-Cas9 platform includes predesigned, ready-to-use guide RNAs to enable rapid assessment of multiple targets across many genes. The application of this platform is greatly expanded by our offering of arrayed crRNA libraries and pooled lentiviral libraries. Both products enable unbiased, powerful loss-of-function screens.

    Edit-R crRNA Libraries

    • Edit-R predesigned crRNA are selected by the Edit-R algorithm as highly functional and specific to their target sequences for more robust, reliable gene knockout
    • Four unique crRNA designs per gene, provided as individuals or a pooled reagent, delivering robust gene knockout for high-confidence phenotypic results
    • Conveniently arrayed in 96-well or 384-well plates and offered as gene family collections. Echo-qualified 384-well plates are available upon request.
    • Also available as crRNA cherry-pick libraries; simply upload your own gene list and customize your plates

    Edit-R Lentiviral sgRNA Arrayed Screening Libraries

    • Edit-R Lentiviral sgRNA are selected by the Edit-R algorithm as highly functional and specific to their target sequences for more robust, reliable gene knockout
    • Up to four unique sgRNA designs per gene, providing multiple data points for increased experimental confidence and stratification of results
    • Conveniently arrayed in 96-well plates of E. coli glycerol stocks and offered as gene family collections
    • Plasmids can be isolated and delivered directly to cells or packaged into lentiviral particles for more difficult cell types

    Edit-R Lentiviral sgRNA Pooled Screening Libraries

    • Pools of specific, algorithm-designed lentiviral sgRNA targeting hundreds or thousands of genes supplied as high-titer, concentrated lentiviral particles (minimum titer of ≥ 5 x 108 TU/mL)
    • 5 to 10 sgRNAs per gene for increased hit confidence and comprehensive genome screening
    • Over 400 positive and negative sgRNA controls in each pool facilitates inter- and intra-pool normalization
    • Enough lentiviral particle volumes provided to perform quality screens at the high average sgRNA fold representation necessary for increased hit confidence and greater biological reproducibility

    Lentiviral Guide RNA

    Selection guide

    When choosing a CRISPR-Cas9 screening platform, there are many considerations in determining the best tools for your experimental needs. Instrumentation, analytical support, and assay type(s) must all be taken into account.

    Supporting data

    Successful screening with CRISPR-Cas9 reagents is highly dependent on the efficiency of gene editing achieved. Both the Edit-R crRNA Libraries and Pooled sgRNA Screening Libraries benefit from the Edit-R algorithm, which selects for highly functional designs.
