    CRISPR Guide RNA

    Lentiviral and synthetic reagents for targeted gene knockout

    Guide RNAs program Cas9 nucleases to cut at a specific genomic location. The design of an effective, functional guide RNA is critical to achieving efficient gene knockout. Take advantage of our algorithm for functional, specific guide RNAs and search our predesigned products for your gene of interest.

    • Synthetic crRNA

      Pre-designed or custom synthesized for rapid knockout studies across many genes

    • Lentiviral sgRNA

      Pre-designed or custom sgRNA as glycerol stocks and high-titer purified lentiviral particles for small- and large-scale studies

    • Synthetic sgRNA

      Custom single guide RNA oligos for CRISPR-Cas9 gene editing

    All Edit-R predesigned guide RNA (synthetic crRNA and lentiviral sgRNA) are designed with a validated algorithm to improve the likelihood of functional knockout, not just double-strand breaks (DSB). By assessing functional phenotypes for thousands of designs, then validating our design rules in other assay systems, we have established rules for determining target sites that are more likely to give efficient cleavage and functional knockout with high specificity. See the Supporting Data tab for more information.

    Edit-R synthetic sgRNA and crRNA can be custom designed to any sequence using the CRISPR RNA Configurator.

    Guide RNAs in the CRISPR-Cas9 system

    In addition to expression of the Cas9 nuclease, the CRISPR-Cas9 system requires a specific RNA moiety to recruit and direct the nuclease activity. These guide RNAs take one of two forms:

    • A long, chemically synthesized trans-activating CRISPR RNA (tracrRNA) plus a chemically synthesized CRISPR RNA (crRNA) designed to cleave the gene target site of interest (Figure 1a)
    • -or-
    • A synthetic or expressed single guide RNA (sgRNA) that consists of both the crRNA and tracrRNA as a single construct (Figure 1b)

    • Edit-R predesigned crRNA

      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 tracrRNA

      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.

    Selection guide

    While the best guide RNA for your experiment may heavily depend on your particular application or cell type, a few basic questions may help to point you in the right direction for product selection.
