本文介绍一种高度灵敏的免疫酶技术.即抗生物素蛋白(avidin)—生物素(biotin)—过氧化物酶复合物技术简称组织学ABC技术,抗生物素蛋白有四个结合生物素的位点,生物素又能与过氧化酶相结合.这是一个三层系统,以生物素标记的第二抗体作为第一抗体和抗生物素蛋白—生物素—过氧化物酶复合物间的桥梁,抗生物素蛋白作为生物素标记的过氧化物酶之间的连接物.同时,生物素标记的过氧化物酶也作为抗生物素蛋白分子间的连接物. This article describes a highly sensitive immune enzyme technology, namely the avidin-biotin-peroxidase complex, referred to as the histological ABC technique, with four avidin-binding biotin- Biotin, in turn, binds to peroxidase, a three-layer system that uses a biotinylated secondary antibody as the primary antibody and avidin-biotin-peroxidase complex Bridges, avidin as biotin-labeled peroxidase link between the same time, biotin-labeled peroxidase also serves as avidin molecules between the connectors.
