酶联免疫吸附试验(又称酵素免疫分析法,Enzyme-linked immunosorbent assay (ELISA),简称酶联法)利用抗原抗体之间专一性键结之特性,对检体进行检测;由于结合于固体承载物(一般为塑胶孔盘)上之抗原或抗体仍可具有免疫活性,因此设计其键结机制后,配合酵素呈色反应,即可显示特定抗原或抗体是否存在,并可利用呈色之深浅进行定量分析。酶联法的一项重要应用为用于HIV检测, 其检测的蛋白一般为HIV的p24蛋白 (P24 capsid protein). 根据待测样品与键结机制的不同,ELISA可设计出各种不同类型的检测方式,主要以三明治法(sandwich)、间接法(indirect)、以及竞争法(Competitive)三种为主,以下为各种方法之介绍。
