Synthetic single-strand DNA oligonucleotide (ssDNA oligo) donors for precise genomic modification with the homology-directed repair (HDR) pathway
Genome engineering has advanced tremendously with the characterization of bacterial and archael CRISPR (clustered regularly interspaced short palindromic repeats) systems and their adapted usage in mammalian cells. The ability to precisely and permanently alter endogenous gene expression through targeted genome editing is a highly effective reverse genetics tool.
Multiple publications have shown the use of the Edit-R genome engineering products to target and cleave DNA in mammalian cells, thereby permanently disrupting gene expression, demonstrating this a new and exciting set of molecular tools to interrogate gene function.
There are two required components for CRISPR gene editing - a guide RNA and a source of Cas9 nuclease – each of which are available in multiple formats. Depending on your cell type and application, some options will be better than others. Browse our entire suite of products, or take a few minutes to view this video, which walks through a few high-level questions to help direct you to the best components for your experiment.

Guaranteed to edit your target! Algorithm-optimized crRNA for genome-wide coverage of human, mouse, or rat genes. Modifications for nuclease resistance improve DNA-free editing. Simply search for your gene!
Edit-R trans-activating CRISPR RNA (tracrRNA) is synthetic, HPLC-purified, long RNA required for use with Edit-R crRNA to form the complex that programs Cas9 nuclease. It is modified for nuclease resistance and can be used with modified or unmodified Edit-R crRNA.

The breadth of the Dharmacon portfolio supports multiple gene editing workflows; choose the one that suits your experimental system and desired outcome.
Gene editing with Edit-R Cas9 Nuclease mRNA or protein and crRNA:tracrRNA is performed by co-transfecting all components with DharmaFECT Duo Transfection Reagent (or other DharmaFECT transfection reagent suitable for your specific cells of interest). One may then observe phenotypes directly. A DNA mismatch detection assay can be used to estimate gene editing efficiency prior to clonal cell line generation and characterization.
Gene editing with Edit-R Cas9 Nuclease Expression Plasmid and crRNA:tracrRNA is performed by co-transfecting all components with DharmaFECT Duo Transfection Reagent. One may then observe phenotypes directly (no enrichment), or enrich for transfected cells, either with cell sorting (with mKate2 plasmid) or puromycin selection (with PuroR plasmid). A DNA mismatch detection assay can be used to estimate gene editing efficiency prior to clonal cell line generation and characterization.
Gene editing with Edit-R Lentiviral Cas9 Nuclease and crRNA:tracrRNA can be carried out in two ways. The left side of the diagram shows enrichment and expansion of the population of cells transduced with Edit-R Lentiviral Cas9 nuclease, then transfected with crRNA:tracrRNA for target gene editing. The right side of the diagram illustrates clonal isolation and expansion to create a more defined Cas9-expressing assay system. Both methods enable straightforward assessment of multiple target sites for multiple genes.
Gene editing with Edit-R Lentiviral Cas9 Nuclease and sgRNA can be done following a mixed cell populations approach (left side), typically for gene knockout screening, or on isolated clonal cells lines (right side) when preferred or required.
Do you have a favorite guide RNA sequence?
Do you require design assistance to ensure Cas9 cleavage in a specific region of your target gene?
Edit-R predesigned crRNA and lentiviral sgRNA provide algorithm-optimized designs for functionality and specificity; but when particular designs or parameters are desired, you can design your own crRNA or sgRNA with our easy-to-use interface.
The Dharmacon CRISPR Design Tool allows you to design or enter your own CRISPR targeting sequences for incorporation into synthetic crRNAs and single guide RNAs (sgRNAs).
Visit the CRISPR Design Tool Workflow page if you need to learn more about designing a custom guide RNA or see the CRISPR Design Tool User Guide for detailed instructions.
