鸡贫血病毒细胞凋亡素基因的原核表达及其免疫学活性
Expression of Chicken Anaemia Virus(CAV) Apoptin Gene in E.coli and Analysis of It′s Immunity
【摘要】 将鸡贫血病毒 (CAV)细胞凋亡素基因克隆入表达性载体 p GEX- 5 X- 3,在大肠杆菌中以融合蛋白的形式获得表达。再以表达产物免疫小鼠 ,制备抗 CAV凋亡素的多克隆抗体。以其对 CAV感染的 MSB1细胞作间接免疫荧光试验(IFA)检测呈阳性 ,表明表达产物保留了其相关的天然抗原特性。
【Abstract】 CAV apoptin gene was inserted into pGEX-5X-3 vector,then expressed by in E.coli in a fusion protein form.The anti-CAV polyvalent antibody was produced from mouse immunized with the fusion protein,and its specificity was detected positively on CAV-infected MSB1 cells by indirect immunoinfluscent assay(IFA).This results showed the expressed protein retained some antigenicities of the native CAV apoptin.
