摘  要：
根据GenBank发表的Hypodermin C(HC)基因序列设计引物,以原核表达载体pET-HC为模板,PCR扩增HC基因,将克隆基因插入到真核表达载体pVAX1中,构建重组真核表达质粒pVAX1-HC。将重组质粒pVAX1-HC转染小鼠胎儿成纤维细胞,以间接免疫荧光法检测HC基因在细胞中表达。用真核表达质粒pVAX1-HC经双侧胫前肌注射昆明小鼠,对小鼠进行体液免疫和细胞免疫研究。结果表明,小鼠血清抗体水平和淋巴细胞增殖水平明显高于非免疫对照组。本研究成功构建了真核表达质粒pVAX1-HC,为纹皮蝇核酸疫苗研发奠定了基础。

摘  要：
The primers were designed according to sequence of Hypodermin C(HC) gene in GenBank,and HC gene was amplified by PCR using the pET-HC as template,then cloned into the eukaryotic expression vector pVAX1 to construct a recombinant expression plasmid named pVAX1-HC.The recombinant plasmid pVAX1-HC was transfected into the mice embryonic fibroblasts(MEF),and Hypodermin C expression was detected in vitro by indirect immunofluorescence method.After intramuscular injection into Kunming mice with pVAX1-HC in order to research the humoral immunity and cellular immunity,the results showed that the serum antibody levels and lymphocyte proliferation levels were significantly higher than that in the control group.This eukaryotic expression plasmid can develop as novel DNA vaccine of hypodermosis.
