Confidence in your knockout experiment
Edit-R CRISPR guide RNAs are guaranteed to edit the target gene-of-interest, so you can be confident in your knockout result – see guarantee tab for details.
Our guide RNAs are designed using a validated algorithm to achieve functional gene knockout with high specificity. By assessing phenotypes for thousands of designs, then validating our design rules in multiple assay systems, we have established standards for determining optimal knockout target sites.
Visit our application page to learn more about the Edit-R CRISPR-Cas9 gene editing system.
Flexibility to fit your workflow
We offer Edit-R CRISPR guide RNA in pools or as individual reagents in a variety of formats to fit many different experimental workflows.
- Synthetic single guide (sgRNA) or two part crRNA:tracrRNA reagents can be co-transfected with Cas9 mRNA or protein for DNA-free workflows.
- Lentiviral sgRNA are recommended for editing in difficult-to-transfect cells.
- All-in-one lentiviral sgRNA + Cas9 offers a single-reagent knockout workflow.
- Custom design synthetic or lentiviral guide RNAs for additional species, alternative nucleases or any target location using the CRISPR Design Tool.

CRISPR guide RNA
Edit-R synthetic guide RNA & controls
Genome wide synthetic sgRNA designs guaranteed to edit your gene of interest. The design algorithm maximizes the potential for functional protein knockout while minimizing off-target editing through stringent specificity checks.
Species-specific synthetic sgRNAs targeting well-characterized genes, as well as mismatch detection assay primers, to determine the effectiveness of your gene editing conditions for maximal efficiency.
Non-targeting controls to evaluate cellular responses to CRISPR-Cas9 components in the absence of gene target-specific sgRNA.
Guaranteed to edit your target! Algorithm-optimized crRNA for genome-wide coverage of human and mouse genes. Modifications for nuclease resistance improve DNA-free editing.
Trans-activating CRISPR RNA (tracrRNA) is required for use with Edit-R synthetic crRNA to form the complex that programs Cas9 nuclease.
Edit-R lentiviral sgRNA & controls
Combined Cas9 and sgRNA expression for efficient gene knockout & unparalleled specificity; available as glycerol stocks and high-titer purified particles.
All-in-one lentiviral sgRNA controls to verify DNA double-strand breaks and gene editing efficiencies.
All-in-one lentiviral sgRNA constructs bioinformatically designed to not target any gene in human or mouse genomes.
Guaranteed to edit your target, algorithm-optimized sgRNA for genome-wide coverage of human or mouse genes. Provided as high-titer lentiviral particles or glycerol stocks.

The Edit-R guarantee
We guarantee that EVERY predesigned guide RNA will provide successful editing at the target site when delivered as described in the Edit-R technical manuals.
The Edit-R guide RNA guarantee is valid when used with any wild type S. pyogenes Cas9 nuclease, including mRNA, expression plasmid, protein, or stable Cas9 expression, and Edit-R crRNAs must be used with Edit-R tracrRNA for the guarantee to apply.
Analysis of editing of the treated cell population must be shown using a T7EI or Surveyor mismatch detection assay. If successful editing is not observed for a predesigned Edit-R guide RNA while an appropriate side-by-side Edit-R positive control is successful, a one-time replacement of a different predesigned Edit-R guide RNA of the same format and quantity will be provided at no cost.
A replacement will only be approved upon discussion with our Technical Support team.
Successful editing at the DNA level does not always lead to functional gene knockout; it is recommended to test multiple guide RNAs to determine the most effective guide RNA for knockout of your target gene.
This guarantee does not extend to any accompanying experimental costs, does not apply to guide RNAs ordered via the CRISPR Design Tool, and will not be extended to the replacement guide RNA.
