Custom CRISPRa sgRNA Vectors    

CRISPR activation (CRISPRa) is a CRISPR tool that provides a powerful way to activate genes on a large scale in a focused manner. CRISPRa takes full advantage of a modified version of dCas9, a Cas9 mutation that does not have endonuclease activity, and fused with transcriptional activators. The screening of CRISPR-based transcriptional activation has been used to research mechanisms of human diseases, screen drug targets, and establish causal relationships between gene expression and cell fate determination. In addition, CRISPR-based gene activation is expected to be used to target endogenous gene regulatory elements to increase the expression level of normal gene copies to correct diseases caused by haploid function.

For this application, CRISPR/Cas9 PlatformCB provides customized CRISPRa sgRNA vectors construction services, including sgRNA design and viral vector packaging, which can be applied to both easy-to-transfect cells and hard-to-transfect cells. Just send us the gene ID you are interested in, we will design, clone and provide this powerful technology for you. Our custom CRISPRa sgRNA can be purchased separately or as a pre-packaged virus.
