摘要
为了对囊尾蚴病的免疫诊断提供有价值的单克隆抗体(McAh),我们应用杂交瘤技术,通过对骨髓瘤细胞NS-1与用猪囊尾蚴囊液抗原免疫的BALB/C小鼠脾细胞融合试验及反复筛选和多次克隆化,建立了3株分泌抗猪囊尾蚴抗原的McAb杂交瘤细胞株1D_4、4E_(11)和4E_(12)。其分泌的抗体具有很强的种的特异性,与细粒棘球蚴和肥颈绦虫囊尾蚴抗原均不发生交叉反应。免疫球蛋白亚类鉴定表明3株均属IgGI。经蛋白质转移电泳试验(Western blot)确定,与所获McAb发生特异反应的抗原是猪囊尾蚴头节囊壁(SCW)抗原分子量为25kDa和17kDa的蛋白组分。
In order to produce valuable monoclonal antibodies for immunodiagnosis of cysticerco-sis, hybridoma technique was adopted using the fusion of splenic lymphocytes from BALB/c mice immunized with Cysticercus cellulosae antigens and the myeloma cell line NS-1. Through screening and cloning, three monoclonal antibody cell lines have been established. Im- munoglobulin subclasses of 3 lines were determined to be IgGl. These monoclonal antibodies were found to be highly specific and without cross reaction with Echinococcus granulosus hy-datid cyst and Cysticercus fasciolasis. Antigen fractions specifically reacting to monoclonal antibodies were demonstrated with Western blot method. The results showed that specific reaction bands of SCW located in 25 kDa and 17 kDa regions.
