| 摘 要： | 从乙肝阳性人血清中克隆HBV含前s区表面抗原基因（PreSZ＋S），将其插入到杆状病毒转移质粒PVL1393中，并与昆虫病毒ACNPVDNA共转染Sf9昆虫细胞，筛选出重组病毒。用乙肝放免（RIA）试剂盒及EIAPreS2－Ag检测试剂盒检测重组病毒感染的Sf9细胞，表明细胞中有HBsAg及PreS2－Ag存在。将重组病毒感染的细胞免疫小鼠，在小鼠血清中能检测到anti-HBsAg及anti-PreS2抗体。

| Abstract: | HBV DNA was extracted from HBsAg positive serum and used for the amplication of the whole gene coding HBV surface antigen middle protein by PCR. The gene was inserted into a baculovirus transfer vector pVL1393 and cotransfected into Sf9 insect cells with wild AcNPV DNA,then recombinant virus was screened out. By using RIA and EIA kits, HBsAg and PreS2-Ag were detected out in Sf9 cells infected with the recombinant virus,and the corresponding antibodies of them were also detected out in the serum of mice imunized with the cells. |
