CRISPR cut cartoon button Cut Wild type Cas9 efficiently generates double strand breaks (DSBs) at sequences homologous to co-expressed gRNA.
CRISPR nick cartoon button Nick A mutated "nickase" version of the Cas9 enzyme generates a single-strand DNA break (Nick), instead of a double-strand DNA break (Cut).
CRISPR interfere cartoon button 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.
CRISPR activate cartoon button Activate A catalytically inactive Cas9 (dCas9) fused to an activator peptide can activate or increase gene expression.
CRISPR cut cartoon button dCas9-FokI A catalytically inactive Cas9 (dCas9) fused to FokI nuclease to generate double strand breaks (DSBs, Cut) at sequences homologous to two co-expressed gRNA.
CRISPR purify cartoon button Purify Isolate specific genomic regions of interest using a catalytically inactive Cas9 (dCas9) fused with an epitope tag(s).
CRISPR visualize cartoon button Visualize Visualize specific genomic regions of interest using a catalytically inactive Cas9 (dCas9) fused to a fluorescent protein.
CRISPR libraries cartoon button Screen Use pooled CRISPR libraries to screen for genes involved in specific biological processes.
empty gRNA cartoon button Validated gRNAs Experimentally validated, pre-made gRNA plasmids to specific genes.
Round_Empty_gRNA_Expression_Icon.png Empty gRNA Vectors Select a gRNA plasmid based on a variety of factors, such as selectable marker or cloning method.
