CRISPR-Cas9 Gene Editing

Optimized tools for high-confidence genome engineering

The Dharmacon Edit-R CRISPR-Cas9 platform greatly simplifies the workflow of permanently knocking out genes. Our approach includes predesigned, ready-to-use DNA and RNA components and enables fast assessment of multiple target sites per gene for multiple genes. We hold a license from the Broad Institute to provide CRISPR reagents for research use.

CRISPR genome engineering

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.

Choosing the right products for a CRISPR Experiment

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.

CRISPR RNA Configurator

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 RNA Configurator allows you to design or enter your own CRISPR targeting sequences for incorporation into synthetic crRNAs and single guide RNAs (sgRNAs).

See the CRISPR RNA Configurator User Guide for detailed instructions.
