摘要: 为寻找与猪流行性腹泻病毒(porcine epidemic diarrhea virus, PEDV)相互作用的Vero E6细胞蛋白,深入研究病毒感染机制,本试验建立了一个Vero E6 细胞酵母杂交cDNA文库。采用Trizol试剂从培养的Vero E6细胞中提取细胞总RNA,通过SMART技术合成双链cDNA,并利用同源重组的方法构建Vero E6 细胞的酵母cDNA文库。结果显示,文库滴度为9.7×108CFU/mL,插入的双链cDNA片段大小为0.5~3 kb,平均长度约为1.6 kb,文库重组率为87%,此文库可以用来筛选与病毒相互作用的Vero E6蛋白。该文库的构建为发现和研究与PEDV结构蛋白相互作用的宿主细胞蛋白奠定基础。

Abstract: To seek out proteins which interact with structural proteins of porcine epidemic diarrhea virus (PEDV) in Vero E6 cells and study the mechanisms of viral infection.We created a Vero E6 cDNA yeast hybrid library. The total RNA of Vero E6 was extracted using Trizol method, and double strands cDNA was synthesized by SMART technique. We created a Vero E6 cDNA library by using homologous recombination in yeast. The results showed that the titer of cDNA library was 9.7×108 CFU with the average of inserted fragments about 1.6 kb, and the recombination rate was 87%. These data indicated that the yeast two-hybrid cDNA library of Vero E6 was successfully constructed and might be useful for screening the host proteins interacting with structure protein of PEDV.
