概述

    化学发光技术是近二十年来发展非常迅速的非放射性免疫分析技术。

    化学发光免疫测定(Chemiluminesent ImmunoassayCLIA)是免疫测定技术继酶免技术(EIA)、放免技术(RIA)、荧光免疫技术(FIA)之后发展的一项新兴测定技术。由于这种测定具备很高的特异性和很小的干扰,因此,如同RIAFIA等一样利用免疫反应的特异性和化学发光本身的信号特异性形成了目前所说的化学发光免疫测定(CLIA)技术。

2、 工作原理

    化学发光免疫分析仪是通过检测患者血清从而对人体进行免疫分析的医学检验仪器。将定量的患者血清和辣根过氧化物(HRP)加入到固相包被有抗体的白色不透明微孔板中,血清中的待测分子与辣根过氧化物酶的结合物和固相载体上的抗体特异性结合。分离洗涤未反应的游离成分。然后,加入鲁米诺Luminol发光底液 ,利用化学反应释放的自由能激发中间体,从基态回到激发态,能量以光子的形式释放。此时,将微孔板置入分析仪内,通过仪器内部的三维传动系统,依次由光子计数器读出各孔的光子数。样品中的待测分子浓度根据标准品建立的数学模型进行定量分析。最后,打印数据报告,以辅助临床诊断。
