| 摘 要： | 为了开发新型高效疫苗预防锦鲤疱疹病毒病,以单壁碳纳米管(SWCNT)作为运输载体,构建锦鲤疱疹病毒(KHV)ORF149核酸疫苗。首先构建pcDNA3.1(+)-ORF149重组质粒,通过瞬时转染和免疫印迹分析确定其表达情况,然后通过1,3-偶极环加成反应法将重组质粒与SWCNTs进行偶联,最后通过扫描电镜观察和核酸电泳鉴定其偶联是否成功。结果表明,构建的重组质粒转染细胞后经免疫印迹分析和间接免疫荧光试验均能检测到特异性信号;在核酸琼脂糖凝胶电泳中,构建的重组疫苗电泳条带消失;在场发射扫描电镜观察下,与重组质粒进行偶联的SWCNTs和空白SWCNTs形态差异明显。

| Abstract: | In order to develop a new type of highly effective vaccine against Koi Herpesvirus(KHV)disease,a single-walled carbon nanotube(SWCNT)was used as a transport vector to construct a KHV ORF149 nucleic acid vaccine. The recombinant plasmid pcDNA3.1(+)-ORF149 was firstly constructed,and its expression was confirmed by transient transfection and immunoblot analysis. Then,the recombinant plasmid was conjugated to SWCNTs by 1,3-dipolar cycloaddition reaction. Scanning electron microscopy and nucleic acid electrophoresis was conducted to identify whether the conjugation was successful. The results showed that specific signals were detected with constructed recombinant plasmid in both immunoblot analysis and indirect immunofluorescence assay after transfection. In the nucleic acid agarose gel electrophoresis,the electrophoretic band of the constructed recombinant vaccine disappeared. Under the observation of scanning electron microscopy,the morphologies of the conjugated SWCNTs with the recombinant plasmid and blank SWCNTs were significantly different. |
