Addgene is working with the leading scientists in the field to assemble the reagents and information you need to use the CRISPR/Cas9 technology in your own lab.
|Cut||Wild type Cas9 efficiently generates double strand breaks (DSBs) at sequences homologous to co-expressed gRNA.|
|Nick||A mutated "nickase" version of the Cas9 enzyme generates a single-strand DNA break (Nick), instead of a double-strand DNA break (Cut).|
|Interfere||A catalytically inactive Cas9 (dCas9) can knockdown gene expression by interfering with transcription. The dCas9 can sometimes be fused to an additional repressor peptide.|
|Activate||A catalytically inactive Cas9 (dCas9) fused to an activator peptide can activate or increase gene expression.|
|Purify||Isolate specific genomic regions of interest using a catalytically inactive Cas9 (dCas9) fused with an epitope tag(s).|
|Visualize||Visualize specific genomic regions of interest using a catalytically inactive Cas9 (dCas9) fused to a fluorescent protein.|
|Screen||Use pooled CRISPR libraries to screen for genes involved in specific biological processes.|
|Empty gRNA Vectors||Select a gRNA plasmid based on a variety of factors, such as selectable marker or cloning method.|
CRISPRs for use in Mammalian systems are listed under the Browse by Function links above.
