Recombinatino polypeptide or chemically synthesized polypeptide antigen is used to immunize the mammal to obtain polyclonal antibody and the nonconservative amion acid sequence of the antiboby to N-terminal with recognition site qBrn-2 of development regulatory protein qBrn-2. The antibody does not recognize other POU structure domain protein, and recognizes specifically qunique protein in Western imprinting experiment. The qBrn-2 expression mode obtained immunohistochemistry process is identical with the resulted height of in-situ molecular hydridization.

以重组多肽或化学合成多肽为抗原免疫哺乳动物获得的多克隆抗体，这一抗体对发育调控蛋白qBrn－2的识别位点为qBrn－2的N－末端的非保守性的氨基酸序列，该抗体不识别其它POU结构域蛋白；在Western印记实验中，该抗体特异地识别单一的蛋白；利用免疫组织化学接示的qBrn－2表达模式与分子原位杂交的结果高度一致。

College of Veterinary Medicine,Gansu Agricultural University,Lanzhou 730070,ChinaAbstract: To obtain the hybridoma cell line specific to 45W-4BX antigen of Taenia solium oncosphere,the recombinant plasmid pGEX-4BX containing TSO45W-4BX gene was highly expressed in Escherichia coli induced with IPTG.
