The synthesized cDNA is a continuous band less than 6. 0kb shown on x-film through α〓PdCTP which was inserted in the first strain of cDNA. The titer of the Ha-cDNA library was about 1. 5×10〓cfu/ml which could represent all protein-encoding sequences from Hz-AM1 cells; Namely, the cDNA library has representativity. After the successful construction of the Ha-cDNA library, the open-reading frame of vp39 gene of Heliothis armigera was then fused in frame with the Ga14-DNA-binding domain in the pGBT9 plasmid and the fusion protein Ga14-VP39 was expressed in yeast to be used as bait protein.

在成功构建棉铃虫细胞Hz-AM1cDNA文库的基础上，本文接着将棉铃虫核型多角体病毒衣壳蛋白VP39（HaNPV-VP39）基因克隆到酵母双杂交系统(yeasttwo-hybrid system)中的质粒pGBT9上。pGBT9上含有酵母菌转录激活因子GAL4 DNA结合域的编码区（GAL4-DBD），使克隆到质粒pGBT9上的HaNPV-vp39基因与GAL4-DBD基因融合，在酵母菌中表达DBD-vp39融合蛋白，该融合蛋白即为酵母双杂交系统中的诱饵蛋白。
