摘要: 从猪小肠制备碱性磷酸酶,再用戊二醛一步法结合羊抗人IgG;该酶结合物的最高滴度可达1:6 400.以日本血吸虫虫卵粗抗原包板,检测确诊血吸虫病病人血清54份,符合率为100%。测定血吸虫病病人、正常人、小学生、肺吸虫病病人、华支睾吸虫病病人、姜片虫病病人和丝虫病病人血清的阳性率分别为96.5%(222/230)、2.1%(6/280)、0%(0/212)、2.8%(1/35)、5.1%(5/98)、0%(0/5)和6.3%(5/79),表明该酶结合物用于ELISA诊断日本血吸虫病具有较高的敏感性和一定的特异性。

Abstract: Self-made alkaline phosphatase (AKP) was prepared from pig intestine and then coupled with goat antihuman-IgG by one step glutaraldhyde method, the maximum titer of the conjugate being 1:6 400.Using Schistosoma japonicum soluble egg antigen as coating antigen, the positive rate of AKP conjugate was 100% in 54 proven patients with schistosomiasis japonica. The positive rates for sera from normal adults, pupils, patients of schistosomiasis, para gonimiasis, clonorchiasis, fascialopsiasis and filariasis were 2.1% (6/280), 0% (0/212), 96.5% (222/230), 2.80(1/35), 5.1%(5/98), 00(0/5) and 6.3%(5/79), respectively. The results showed that the AKP conjugate used in ELISA for schistosomiasis presented higher sensitivity and relative specificity.
