摘要
为揭示血吸虫生长发育机理,深入研究血吸虫与宿主、血吸虫雌雄虫之间蛋白质的相互关系,本研究选取血吸虫进入终末宿主体内18天时的虫体(发育成熟初期),采用Clontech Matchmaker技术成功构建日本血吸虫的酵母双杂交cDNA文库。该文库具有基因多样性和足够大的库容量,库容量为2.5×10^6pfu/mL,插入的双链cDNA片段的长度在0.25~2.0kb之间,文库重组比率为97.9%,具有良好的代表性。该文库的构建为筛选相互作用蛋白并进一步阐明其生理意义提供了基础。
To study the interaction between schistosome and vertebrate host, male and females worms of schistosomes, the Yeast Two-Hybrid cDNA library from 18 day Schistosomajaponicum were constructed. The titer of library was 2.5 ×10^6 pfu/mL, the PCR identification showed that recombination rate was 97.9%, in which inserted cDNA fragments's length were between 0.25 kb and 2.0 kb, and the library possess satisfactory representation.
