An enzyme-linked immunosorbent assay (ELISA) incorporating the sensitive biotin-streptavidin system was developed to detect IgG antibodies to tetanus toxoid in human serum. Serum samples obtained from 557 normal persons aged 1-65 years from different areas in New Zealand were tested. The proportion of those immune ranged from 60-93% in males, and from 46-86% in females. In the 1-9 years age group 85% were immune. The indirect ELISA is suitable for serological surveys as it is simple to perform, economical and reproducible.
开发了一种结合敏感生物素-链霉亲和素系统的酶联免疫吸附测定(ELISA),用于检测人血清中破伤风类毒素的IgG抗体。对从新西兰不同地区557名年龄在1至65岁的正常人获得的血清样本进行了检测。免疫者的比例在男性中为60%-93%,在女性中为46%-86%。在1至9岁年龄组中,85%的人具有免疫力。间接ELISA操作简单、经济且可重复,适用于血清学调查。
