半岛bd体育手机客户端 说明

一般描述

Ready to use dCas9-VP64 lentiviral particles enable immediate transduction of a wide range of cell lines. dCas9-VP64 lentiviral particles efficiently and stably integrate dCas9-VP64 and blasticidin resistance cassette linked by a 2A peptide and driven by the EF1 alpha promoter (EF1a-dCas9-VP64-2A-Blasticidin) for strong expression in both dividing and non-dividing cell lines. They are ideal for avoiding the tedious lentivirus production process and are one part of a three part CRISPR system with individual dCas9-VP64. MS2-p65-HSF1 and gRNA expression vectors.

原理

CRISPR/Cas systems are employed by bacteria and archaea as a defense against invading viruses and plasmids. Recently, the type II CRISPR/Cas system from the bacterium Streptococcus pyogenes has been engineered to function in eukaryotic systems using two molecular components: a single Cas9 protein and a non-coding guide RNA (gRNA). The Cas9 endonuclease can be rendered inactive (dCas9) with mutations to the two protein domains, RuvC and HnH (D10A and H840A respectively), which are responsible for nuclease activity. The nuclease deficient protein can then be fused with the transcriptional activator VP64 and used in conjunction with a guide RNA modified with MS2 RNA aptamers that function to recruit the additional transcriptional coactivators p65 and HSF1. The assembled SAM complex is then used as a cargo delivery system to target gene promoters, enabling site-specific transcriptional activation of the gene of interest.
