摘　　要：利用杆状病毒表达系统在家蚕BombyxmoriL.细胞BmN中表达家蚕30K蛋白,以亲本病毒BmPAK6为对照,将重组病毒Bm/r-30K分别感染BmN细胞及家蚕幼虫,观察其感染后不同时间的凋亡及存活率。与对照相比,重组病毒感染后的BmN细胞的存活率明显高于对照组,并且感染的家蚕幼虫存活时间也较长,表明体内过量表达家蚕30K蛋白有助于延长其细胞及幼虫的存活。The 30K protein was successfully expressed in the Bombyx mori L. （Bm） cells by baculovirus system. B. mori cells and larvae were infected with the recombinant baculovirus（ Bndr-30K）, respectively. The viability of cells and larvae were assayed at various times post-infection and BmPAK6 was used as a control. The viability of BmN cells infected with baculovirus（Bndr-30K） was higher than that of the cells infected with BmPAK6 virus, the viability and surviving time of B. mori larvae were increased as well. The results indicate that over-expression of the B. mori 30K gene contributes to increase the＇surviving time of BmN cells and larvae.
