摘要
A transformed cell line was constructed fromMythimna separata cells Ms7311 by lipofection methodTMs7311 cells were generated using a double selection tech-nique involving a selection in the antibiotic Zeocin, followedby a second round of selection by exhibiting cell characteri-zation. A cell clone expressing p35 was obtained with highlevel of AcMNPV and recombinant proteins. Compared withwild type Ms7311 cells, the cell clone showed increased resis-tance to Actinamycin D-induced apoptosis and a profoundresistance to nutrient development (PBS). When the cellclone was infected with recombinant baculoviruses express-ing secreted alkaline phosphatase (SEAP) and β-galactosi-dase, expression of the recombinant proteins from TMs7311cells exceeded that from parental Ms7311 cells. Production ofbudded virus and occlusion body was significantly higherthan that from parental cells Ms7311.
