CRISPRiTest Functional dCas9 Repressor Assay Kit for Mammalian Cells (for 5-15 cell lines) Add to Cart
|Please note:||Genetically modified organism (GVO), see General Terms.|
The CRISPRiTest Functional dCas9-Repressor Assay Kit allows you to measure a functional dCas9-Repressor (e.g., dCas9-KRAB) in any mammalian cell system. The CRISPR interference (CRISPRi) system is a modification of the original CRISPR system that uses a targeted sgRNA molecule to direct a “catalytically dead” Cas9 (dCas9) fused with a gene repressor, for example, KRAB (i.e., dCas9-KRAB), to a target a gene promoter on genomic DNA. The recruitment of the Cas9-Repressor to the promoter region then blocks expression of the gene regulated by the promoter.
The CRISPRiTest Kit provides reagents to measure the repressor efficiency of any Streptococcus pyogenes dCas9 repressor (dCas9-Rep) hybrid protein in cells designed to be used for CRISPRi experiments, using a FACS-based assay.
The Kit contains packaged lentiviral constructs expressing dCas9-Rep regulated GFP and a non-regulated RFP protein. The Kit provides enough reagents for 5-10 cell lines.
