摘要: 本研究应用噬菌体抗体库技术筛选禽流感亚型病毒Fab抗体,并建立相应ELISA检测方法。用禽流感亚型混合疫苗免疫小鼠,取其脾脏提取总RNA用于扩增免疫球蛋白轻链和重链基因,克隆至噬菌粒pComb3,然后转化入感受态细胞XL1-Blue中,以1012 CFU辅助噬菌体VCSM13进行感染后,获得Fab抗体库容量为8×107 CFU。以H5N1病毒为抗原进行4轮亲和筛选,获得特异性结合的克隆,利用获得的特异性克隆进行ELISA检测方法的建立。

Abstract: Fab antibody of avian influenza virus subtypes was screened by phage antibody library,and an ELISA detection method was established. Mice were immunized with vaccine mixed of subtypes of AIV, the total RNA was extracted from harvested spleens, immunoglobulin light-chain and heavy-chain gene was amplificated with the template of total RNA, and cloned into phagemid pComb3, the recombinant phagemid pComb3 was transformed into XL1-Blue competent cells, after infected with helper phage VCSM13, Fab antibody library of 8?107 CFU was obtained. Specific clones anti-H5N1 virus was obtained after 4 rounds of screening,ELISA detection method was established with specific clones.

Key words: avian influenza virus; phage antibody library; establishment of detection method
