摘要: [目的]构建犬细小病毒(CPV)VP2基因真核表达质粒,为研究核酸疫苗奠定基础.[方法]根据CPVVP2基因序列设计特殊引物,采用PCR方法从疑似"犬细小病毒"的患犬粪便基因组中扩增VP2基因,将其克隆至真核表达载体pcDNA3.1(+),测序验证后,小白鼠尾静脉注射瞬时表达VP2基因,8 h后取小白鼠肝脏提取总RNA,进行RT-PCR扩增.[结果]在病犬粪便基因组中扩增得到1 755 bp的VP2基因片段,并构建了真核表达质粒pcDNA3.1(+)-VP2,从瞬时表达的小白鼠肝脏总RNA中可扩增到目的条带.[结论]成功构建了犬细小病毒VP2基因真核表达重组质粒,并在小白鼠体内进行了瞬时表达.
