A two-plasmid CRISPRi system for that does not require antibiotic maintenance was developed. pJAK184.tetR.PT5-3.dCas9 contains an optimized tetracycline-inducible for chromosomal insertion. pJC.15A.sgRNA.TA encodes a toxin-antitoxin system for stable maintenance, and , which is exchangeable for a customized sgRNA. We demonstrate the knockdown of the essential gene .
开发了一种不需要抗生素维持的双质粒CRISPRi系统。pJAK184.tetR.PT5 - 3.dCas9包含一个用于染色体插入的优化四环素诱导元件。pJC.15A.sgRNA.TA编码一个用于稳定维持的毒素 - 抗毒素系统,以及一个可替换为定制sgRNA的元件。我们展示了必需基因的敲低。
