摘要
作者首次从猪囊尾蚴中提取胶原蛋白,用紫外分光仪、SDS-PAGE、透射电镜和ELISA等方法对猪囊尾蚴胶原蛋白进行了初步分析。表明:(1)猪囊尾蚴中含有一定量的胶原蛋白;(2)胶原蛋白主要以Ⅰ型为主,分子量在80kDa~130kDa之间;(3)通过酶联免疫吸附实验,检测其抗原性。对42例脑囊虫病患者血清IgG抗体的检测,阳性率达88.1%,而对30例正常人检测结果均为阴性。说明囊尾蚴胶原蛋白对人具有很强的免疫性,其抗原决定簇可刺激机体产生特异性IgG抗体。因此猪囊尾蚴胶原蛋白是具有很强的抗原性的一组蛋白质,有望成为囊虫病新的免疫诊断用抗原。
Cysticercus collagen is fistly extracted from cysticercusand preliminarily analysed with ultraviolet spectrophotometer,SDSPAGE,transmission electron microscope(TEM) and ELISA.The resules revealed:There are a certain amount of collagen in cysticercus;The major collagen which the molecular weight are 80130 kDa are belong to tape ;42 patients with cysticercosis and 30 cases of normal persons are tested with ELISA to determine the specility IgG in the serum.The positive rate is 881%.So cysticercus collagen possess stronger immunity and contains a group of protein possessing intensive antigenicity.It is definitely worth whilewith respect to the antigens of cysticercosis immunodiagnosis.
