(Courtesy of Stanley Qi) CRISPRKit works in a similar way, though it employs dCas9, or “dead” Cas9, a deactivated version of the Cas9 enzyme unable to cut DNA. “Whereas CRISPR-Cas9 is ...

The researchers wanted to test if they could reverse these changes using epigenomic editing. So, they employed the CRISPR-dCas9 system. Like its widely used sister system CRISPR-Cas9, CRISPR-dCas9 ...

CRISPR is incredibly robust in terms of cutting DNA and targeting ... CRISPRa uses a version of Cas9 that is inactive (dCas9). It cannot cut DNA, but it progressively binds to targets using guide RNAs ...

It's CRISPR, without the cut. The Horizon CRISPRi system uses a deactivated Cas9 nuclease (dCas9) fused to our proprietary SALL1-SDS3 repressor construct to block transcription of target genes, ...

Following these screens, the researchers tested a third tool — a CRISPR-based demethylase (Tet1-dCas9). This enzyme removes methylation, a chemical mark that silences the maternal allele.
