摘要
目的:构建和鉴定水牛18SrRNA干扰真核表达载体,为进一步研究18SrRNA功能奠定基础。方法:人工设计合成水牛18SrRNA-sh565干扰序列,经基因重组定向克隆插入到真核表达载体pGPH1/GFP/Neo,随机挑选2个克隆菌提取质粒并进行酶切和测序鉴定。结果:质粒酶切和测序结果显示,siRNA寡核苷酸按正确方向和序列插入质粒。结论:成功构建pGPH1/GFP/Neo-buffalo-18S rRNA-sh565干扰表达质粒。
Objective: To construct and identify siRNA expression plasmid for interference buffalo 18S rRNA. Methods: Designed buffalo-18S rRNA-sh565 oligonucletides were chemically synthesized and inserted into pGPH1/GFP/Neo vector after annealing, then transformed into E.Coli DH5α. The recombinant plasmid was identified by restriction endonuclease and DNA sequencing. Results: DNA sequencing showed the siRNA oligonucletides were correctly inserted into the eukaryotic expression vector pGPH1/GFP/Neo. Conclusion: siRNA expression plasmid for interference buffalo 18S rRNA is successfully constructed and lays the foundation for further study of 18S rRNA
