Objective To construct the recombinant plasmid harbouring the encoding gene of Mus musculus metallothionein Ⅱ.

目的 构建含有小鼠Ⅱ型金属硫蛋白基因的真核表达载体,为进行MT抗氧化作用的体内功能实验奠定基础。

Some of them were ligated to the plasmid vector pCR 2.1 andsequenced,respectively.

Necropsies were performed at 21 days post-challenge, the lymph nodes in the nonvaccinated but challenged pigs were larger than those of vaccinated pigs. The PCV2 genomic copy loads in lymph nodes were reduced in vaccinated pigs. Moderate amounts of PCV2 antigen were detected in most lymphoid tissues of nonvaccinated pigs. These data indicated that when given intramuscularly in pigs, the chimeric PCV1-2 live virus and recombinant plasmid induces protective immunity against PCV2 infection and could potentially serve as an effective vaccine.

攻毒后21天攻毒对照组猪淋巴结比免疫组猪显著肿大,免疫组猪血清、淋巴结中PCV2病毒载量低于对照组,攻毒对照组猪淋巴结中PCV2抗原含量高于免疫组,这些结果表明嵌合型猪圆环病毒PCV1-2及真核表达质粒肌肉注射免疫商品猪后,对PCV2感染能产生保护性免疫应答,有可能成为候选疫苗。

Methods: The medicinal plant Rheum wittrochii Lundstr., was genetically with Ri plasmid harbouring in Agrobacterium rhizogenes 9402 strain to induce hairy roots; transformed the opines from the hairy roots were assayed by paper electrophoresis; the contents of free anthroquinones such as aloe-emodin, rhein, chrysophanol, emodin, physcion, 8-O-methylchrysophanol from the hairy roots were quantitatively determined by HPLC technique.

用发根农杆菌Agrobacterium rhizogenes 9402 所含Ri质粒遗传转化药用植物天山大黄以诱导发根用纸电泳法检测发根中冠瘿碱的存在;用高效液相色谱法测定发根中芦荟大黄素、大黄酸、大黄酚、大黄素、大黄素甲醚、大黄酚-8-甲醚等游离蒽醌化合物的含量。
