摘  要:
本文以猪带绦虫成熟虫卵、孵化激活的六钩蚴以及人工感染的囊尾蚴为原始材料 ,采用 Promega试剂盒法分别分离提取总 RNA和m RNA,反转录合成 c DNA,并用а-3 2 P CTP掺入法放射测定其含量。实验表明 :合成的猪带绦虫虫卵、六钩蚴和囊尾蚴的 c DNA含量高 ,均可达 2 50 0 ng,片段大小在 3 0 0 bp以上 ,可满足构建不同发育阶段 c DNA基因文库的需要

摘  要:
Total RNA, mRNA of Egg,Oncosphere and Cysticercus cellulosae from Taenia solium were extracted by Promema company reagent kits. The first strand cDNA was synthesized by using AMV reverse transcriptase, and following synthesized second strand of cDNA of different development stages of Taenia solium and detected its content with α 32 P CTP radiation method. The results show that the quantity and the fragment length of the three types of cDNA are above 2500 ng and 300 bp, respectively. Those meet the needs of constructi ng its cDNA library.
