对氧磷单克隆抗体的研制及鉴定

Production and identification of anti paraoxon monoclonal antibodies

重氮化法使对氧磷（Ｅ６００）与牛血清白蛋白（ＢＳＡ）、血蓝蛋白偶合合成人工抗原。用人工抗原Ｅ６００－ ＢＳＡ免疫Ｂａｌｂ／ｃ小鼠，然后将ＳＰ２／０小鼠骨髓瘤细胞和Ｅ６００－ ＢＳＡ免疫的Ｂａｌｂ／ｃ小鼠脾脏细胞融合，成功的建立了能分泌抗对氧磷单克隆抗体的杂交瘤细胞株。并分析了该细胞株的染色体及对其产生的单克隆抗体的类型、特异性、亲和力进行了鉴定和检测。上述杂交瘤细胞连续传代或冻存１０周。

Paraoxon(E600)was conjugated to bovine serum albumin(BSA) or tachypleus tridentatus hemocyanin(TTH) by diazotization. Two hybridoma cell lines secreting monoclonal antibodies(McAb) against paraoxon have been established by fusing mouse myeloma cells and splenocytes from Balb/c mice immunized with E600 BSA.The chromosomes of the hybridoma cell 2B 10 were analyzed. The immunoglobulin of the McAb was classified. The affinity and specificity of this antibody were determinated. The hybridoma cells have fairly reserved the antibody producing capacity after continuously growing or stored in liquid nitrogen for 10 weeks.
