摘要
将奶牛衣原体抗原免疫的 B A L B/c 小鼠脾细胞与 S P2/ O 细胞在聚乙二醇作用下融合, 用间接 E L I S A 试验筛选, 以有限稀释法克隆3 次, 得到6 株分泌抗奶牛衣原体单克隆抗体( Mc Ab) , 选择抗体分泌较高的 G2 、 F23 、 A 株进行详细的研究, 结果表明, 其核内染色体数为9035 、9214 、9442 ; 抗体属性为 Ig G2a 、 Ig G1 、 Ig M, 用交叉 E L I S A 法对3 株 Mc Ab 作特异性分析, 该 Mc Ab 只与奶牛衣原体抗原, 猪衣原体抗原、羊衣原体抗原发生反应,而不与沙眼衣原体抗原、伪狂犬病抗原、布鲁氏杆菌抗原发生反应。
Using Chlamydia Psittaci(CP)antigen to immunize BALB/C mice,then spleen cell from immunized mice and SP 2/O myeloma cells were fused by PEG.Hybridoma supernatants were screened by indirect ELISA.By 3 times Limiting dilution, 6 hybridoma cell strains secreting monoclonal antibody to CP were established.With indirect ELISA specificity of 3 McAb is analysed,the McAb only reacted with CP antigen,but not with Pseudorabies Virus(PRV) Brucella abortus and C.trachomatis.
