| Abstract: | P2 gene was amplified with P2 specific primer by polymerase chain reaction (PCR) and was inserted into baculovirus expression vector pFASTBAC. Then recombinant plasmid was identified by digesting and PCR. The plasmid pFASTBAC P2 was transformed into DH10BAC competent E.coli cells. High molecular weight plasmid DNA was extracted from overnight cultures from E.coli white colonies ,which was named Bacmid P2 .The Bacmid P2 DNA was transfected intoSpodoptera fragiperda(Sf 9) cell to harvest virus supernatant and infect fresh Sf 9 cell again.The infected cell DNA was prepared and PCR was performed to identified recombinant virus. The result showed that recombinant virus with P2 was constructed successfully. |
