The nature of the antibodies detectable by the microscopic agglutination test for bovine leptospirosis was examined. Density gradient ultracentrifugation, gel filtration and disulphide-bond-reduction experiments indicated that antileptospiral agglutinating activity was present in both IgM and IgG immunoglobulin fractions. This was confirmed by selective precipitation of specific antibody classes and ion-exchange chromatography.
对通过牛钩端螺旋体病显微镜凝集试验可检测到的抗体性质进行了研究。密度梯度超速离心、凝胶过滤和二硫键还原实验表明,抗钩端螺旋体凝集活性存在于IgM和IgG免疫球蛋白组分中。通过特异性抗体类别的选择性沉淀和离子交换色谱法证实了这一点。
