摘要: 构建日本血吸虫组织蛋白酶B肽链内切酶基因核酸疫苗,PCR、双酶切和DNA序列鉴定后,运用电穿孔技术将重组体pcDNA3.1(+)/Sjcb2转染Hela细胞,免疫细胞化学检测其能在HeLa细胞浆内表达,为抗日本血吸虫核酸疫苗的研制打基础。

Abstract: A recombinant plasmid containing cathepsin B endopeptidase of Schistosoma japonicum (Sjcb2) was constructed, indentified by PCR, restrictive enzyme, digestion and DNA sequencing, and expressed into mammalian cells. Immunochemistry examination showed that the Sjcb2 gene can be expressed in the eukaryotic system, providing a basis for the development of schistosome DNA vaccine.

Key words: Schistosoma japonicum, Cathepsin B Endopeptidase, DNA vaccine, Eukaryotic expression
