Description
Cas9 from Streptococcus pyogenes is the most frequently used Cas endonuclease in CRISPR. dCas9 (deficient Cas9 or Dead Cas9) is a mutant of spCas9. It lacks the ability to cleave double-stranded DNA but is still capable of cleaving only one strand of the genome DNA (so-called “nickase”). Like Cas9, dCas9 can still be localized to the desired genome site guided by specific RNAs (gRNA), thus binding to the targeted genomic loci.
The dCa9 coupled with a fluorescent marker, provides a in vivo fluorescent-imaging tool for visualizing specific genomic loci in real-time in living cells [Reference]. (Note: you need confocal fluorescent microscope for such visualization).
This premade lentivirus express the dCa9-GFP fusion under the enhanced CMV promoter (SuCMV). It does not contain any antibiotic selection. It is used to image specific genomic locus at the presence of the targeting gRNA.
