概述

    化學發光技術是近二十年來發展非常迅速的非放射性免疫分析技術。

    化學發光免疫測定(Chemiluminesent ImmunoassayCLIA)是免疫測定技術繼酶免技術(EIA)、放免技術(RIA)、熒光免疫技術(FIA)之後發展的一項新興測定技術。由於這種測定具備很高的特異性和很小的干擾,因此,如同RIAFIA等一樣利用免疫反應的特異性和化學發光本身的信號特異性形成了目前所說的化學發光免疫測定(CLIA)技術。

2、 工作原理

    化學發光免疫分析儀是通過檢測患者血清從而對人體進行免疫分析的醫學檢驗儀器。將定量的患者血清和辣根過氧化物(HRP)加入到固相包被有抗體的白色不透明微孔板中,血清中的待測分子與辣根過氧化物酶的結合物和固相載體上的抗體特異性結合。分離洗滌未反應的游離成分。然後,加入魯米諾Luminol發光底液 ,利用化學反應釋放的自由能激發中間體,從基態回到激發態,能量以光子的形式釋放。此時,將微孔板置入分析儀內,通過儀器內部的三維傳動系統,依次由光子計數器讀出各孔的光子數。樣品中的待測分子濃度根據標準品建立的數學模型進行定量分析。最後,打印數據報告,以輔助臨床診斷。
