  1. The antigenic and genetic variability of porcine reproductive and respirators syndrome virus ( prrsv ) isolates in china were studied by immunofluoresent monolayer assays ( 1fma ) and restriction fragment length polymorphism ( rflp ) of reverse transcription ( rt ) and polymerases chain reaction ( pcr ) amplified - prrsvorfs fragments among 8 chinese isolates

    本研究通過對豬繁殖與呼吸綜合征病毒( prrsv )國內分離毒株的gp3 、 gp5和n蛋白的抗原性比較及其orf5和orf7遺傳變異性分析,系統研究了國內分離毒株的抗原特性和遺傳學差異。
  2. The purpose of this thesis was to clone two different group 3 lea genes. on one hand, we designed and synthesized a pair of degenerate primers according to the foreign reports. a 500bp dna fragment was obtained with pcr technique from the dna of highly drought - resistant china leymus

    一方面,參照國外報道幾種植物的第三組lea中的hva1基因的相對保守的氨基酸序列,設計併合成一對兼并引物,提取抗旱、耐鹽性強的羊草的dna ,採用pcr技術,擴增出了495bp的一段基因片段。
