A recombinant baculovirus containing the NS1 gene of minute virus of mice was constructed. Optimal expression of the recombinant NS1 protein (rNS1) was achieved by infecting Trichoplusa ni High Five cells at a multiplicity of 10 and incubating them for 72 h postinfection. An enzyme-linked immunosorbent assay (ELISA) with rNS1 as the antigen was evaluated for serologic testing of laboratory rodents. The rNS1 ELISA proved to be a more sensitive method for the detection of antibodies to recently recognized rodent parvovirus species (mouse orphan parvovirus and rat orphan parvovirus) and prototypic parvovirus species (minute virus of mice, Kilham's rat virus, and H-1) than were conventional parvovirus ELISAs that use whole parvovirus virions.
构建了一种含有小鼠微小病毒NS1基因的重组杆状病毒。通过以感染复数10感染草地贪夜蛾High Five细胞并在感染后孵育72小时,实现了重组NS1蛋白(rNS1)的最佳表达。评估了以rNS1作为抗原的酶联免疫吸附测定(ELISA)用于实验啮齿动物的血清学检测。与使用全细小病毒病毒粒子的传统细小病毒ELISA相比,rNS1 ELISA被证明是一种更灵敏的方法,用于检测针对最近识别的啮齿动物细小病毒种类(小鼠孤儿细小病毒和大鼠孤儿细小病毒)和原型细小病毒种类(小鼠微小病毒、基尔汉姆大鼠病毒和H-1)的抗体。
