Description:CRISPR (clustered regularly interspaced short palindromic repeats) interference (CRISPRi) is a widely used genetic technique that allows targeted silencing of transcription in bacteria and mammalian cells. The CRISPRi system is comprised of a catalytically inactive Cas9 (dCas9) protein fused with a transcriptional repressor such as the Krüppel-associated box (KRAB) repressor and a customizable single guide RNA (sgRNA). The Cas9-sgRNA complex binds to DNA elements complementary to the sgRNA and causes a steric block that halts transcript elongation by RNA polymerase, resulting in the repression of the target gene.
pLV-EF1-dCas9-KRAB-T2A-BSD Lentiviral Vector expresses the dCas9-KRAB fusion with EF1 promoter and allows for BSD selection of transduced cells.
Vector Information:This is a lentiviral expression vector that contains all the elements necessary for efficient and high yield viral production. A ubiquitous EF1 promoter drives the expression of the dCas9-KRAB fusion protein and BSD to allow for selection of transduced cells. This vector can be used for stable cell line generation or in combination with a gene specifc sgRNA to repress the target gene expression.

文献和实验-of-function)是让基因表达变多或变强,常用三招:直接构建过表达载体、CRISPR-SAM 激活(CRISPRa)、saRNA 上调。功能缺失(loss-of-function)是让基因表达变少或彻底没,常用:RNAi 干扰(shRNA/siRNA)、CRISPR-Cas9 敲除、cas13d 干扰、dCas9-KRAB 转录抑制。优先级一般是 A>B>C>D,以你的实际需求为导向来选,不是越新越好。说白了,一类是"加量",一类是"减量或撤掉",方向完全相反。 它们分别在细胞里怎么跑 过表达是把编码序列连到
【求助】【求助】将病毒载体感染细胞只有部分基因表达为什么,什么方法可以探究基因未表达的原因
. 谢谢指点! wst207 请问 楼主 T2A是什么序列 有没有相关文献 谢谢。 我只看到过 Self‐cleaving 2A peptide 谢谢 wgfking2003 个人举得需要考虑的问题有: 1、慢病毒本身表达的能力,各种病毒中的基因组元件是否相同。诸如启动子元件,是否有后启动子等都影响病毒中基因元件的表达。目前的基因治疗中CAG 启动子已经被证明明显比CMV好,EF1是很早之前用的启动
circRNA 过表达 敲除 怎么设计?成环机制决定你的靶点在哪
的,得借助带环化臂的专用载体。客户这边要提供标准转录本 ID(比如 hsacirc0074158),吉凯现有现成的带环化臂骨架:质粒端有 GV727(带 ZsGreen1)、GV728(不带荧光),慢病毒端有 GV689(CMV-circRNA-EF1-ZsGreen1-T2A-puromycin)。载体把目的 circRNA 序列夹在左右环化臂之间,靠细胞自身剪接机器把它环化出来。 这里顺带一句:少数 circRNA 还能通过 IRES 元件翻译短肽,这种编码潜力研究可以先用 IRESfinder
