以人绒毛膜促性腺激素(HCG)为抗原,制备出对HCG的多克隆抗体和特异性单克隆抗体,并进行抗体纯化和特性分析,利用辣根过氧化物酶(HRP)分别对其进行了标记.采用双抗夹心ELISA试验,探讨了多克隆抗体与单克隆抗体配对的若干事项.结果表明,利用单克隆抗体和酶标多克隆抗体配对,并用含动物血清的稀释液稀释酶标抗体,可实现对检测原的高特异性和高灵敏度检测.

Using human chorionic gonadotrophin( HCG) as the antigen,polyclonal antibodies and monoclonal antibodies(McAbs) specific for HCG were generated, characterized and highly purified. Then these antibodies were labeled with horseradish peroxidase (HRP). By a double antibody sandwich enzyme-linked immunosorhent assay, several problems of the optimum pairing of polyclonal antibodies and monoclonal antibodies were discussed. The results showed that with monoclonal antibody as trapping antibody and polyclonal antibody labeling with enzyme as testing antibody which should be diluted with animal sera as diluent,the sandwich ELISA had a highly specificity and sensitivity to detect antigen.
