Abstract： 目的 筛选白纹伊蚊C6/36细胞表达连接登革Ⅱ型病毒分子.方法 提取C6/36细胞的总蛋白和膜蛋白,收集和纯化登革Ⅱ型病毒,用12％SDS-PAGE分析C6/36细胞的总蛋白和膜蛋白,转于硝纤膜上,用病毒覆盖蛋白结合实验(VOPBA)筛选C6/36细胞表达连接登革Ⅱ型病毒分子.结果 C6/36细胞的总蛋白和膜蛋白经12％ SDS-PAGE分离后转膜,分别与纯化的病毒液和阴性对照液孵育,用抗登革病毒Ⅰ～Ⅳ单克隆抗体检测,结果显示病毒孵育组在67 000和30 000的位置有特异性的条带出现,而阴性对照组无此条带.结论 用VOPBA法初步从白纹伊蚊C6/36细胞中筛选67 000和30 000等登革Ⅱ型病毒结合分子,其功能的鉴定正在进行.
