以载体蛋白卵白蛋白(OVA)和牛血清白蛋白(BSA)为原料,采用甲醛法制备两种河豚毒素(TTX)抗原。采用非变性凝胶电泳、凝胶过滤和紫外分光光度法分析 TTX 与载体蛋白的偶联。结果表明,非变性凝胶电泳和凝胶过滤可用于定性分析TTX与BSA和OVA的偶联,紫外分光光度法可用于定量分析TTX与BSA和OVA的分子偶联比。用人工 TTX-甲醛-卵清蛋白缀合物免疫的 Balb/C 小鼠的脾细胞与 SP2/0 骨髓瘤细胞融合。通过“有限稀释”克隆产生了分泌抗TTX IgG1亚类单克隆抗体的杂交瘤细胞系(4D5)。 4D5分泌的单克隆抗体(mAb)的分子量、亲和常数和滴度分别为183.69kDa、0.98×108M−1和3.6×105。杂交瘤染色体数目为88-104。
Two kinds of antigens for tetrodotoxin (TTX) were made, using carrier protein ovalbumin (OVA) and bovine serum albumin (BSA), by the formaldehyde method. Nondenaturing gel electrophoresis, gel filtration and ultraviolet spectrophotometry were employed to analyze the coupling of TTX to carrier proteins. The results indicate that nondenaturing gel electrophoresis and gel filtration can be employed to analyze the coupling of TTX to BSA and OVA qualitatively, and ultraviolet spectrophotometry can be employed to analyze the molecular coupling ratio of TTX to BSA and OVA quantitatively. Spleen cells from Balb/C mice immunized with an artificial TTX-formaldehyde-ovalbumin conjugate were fused with SP2/0 myeloma cells. A hybridoma cell line (4D5), which secreted IgG1subclass monoclonal antibody against TTX, was produced by “limiting dilution” cloning. The molecular weight, the affinity constant and the titre of the monoclonal antibody (mAb) secreted by 4D5 were 183.69kDa, 0.98×108M−1and 3.6×105, respectively. The number of the hybridoma chromosome was 88–104.
