摘 要: | 小反刍兽疫病毒(peste des petits ruminants virus,PPRV)属于副黏病毒科、麻疹病毒属成员。本实验室已经证明,该病毒的囊膜糖蛋白H蛋白在未经密码子优化条件下难以在昆虫细胞中表达。本研究首先对其密码子进行优化,然后构建了在昆虫细胞中表达该蛋白的重组杆状病毒。经Western-blot和间接免疫荧光试验表明,该重组杆状病毒在昆虫细胞中能够表达H蛋白,但表达量相对较低。

Abstract: | Peste des petits ruminants virus (PPRV) is classified into the genus Morbillivirus in the family Paramyxovirida. Codon-unoptimized H protein as a viral envelope glycoprotein has not been proven to be expressed in insect cells in our laboratory as yet. In this study,recombinant bac- uloviruses expressing this protein under codon-optimization were produced. Analyses of Western- blot and indirect immunofluorescence showed that the H protein could be expressed in insect cells, but at a relatively low level. |
