    用途

    该试剂盒用于体外定量检测血清、血浆或其他相关生物液体中天然ST/5-HT浓度。

    检测原理

    本试剂盒采用竞争ELISA法。用ST/5-HT抗原包被于酶标板上,实验时样品或标准品中的ST/5-HT与包被的ST/5-HT竞争生物素标记的抗ST/5-HT单抗上的结合位点,游离的成分被洗去。加入辣根过氧化物酶标记的亲和素,生物素与亲和素特异性结合而形成免疫复合物,游离的成分被洗去。加入显色底物(TMB),TMB在辣根过氧化物酶的催化下呈现蓝色,加终止液后变成黄色。用酶标仪在450nm波长处测OD值,ST/5-HT浓度与OD450值之间呈反比,通过绘制标准曲线计算出样品中ST/5-HT的浓度。

    特异性

    可检测样本中的ST/5-HT,且与其它相关蛋白无明显交叉反应。

    重复性

    板内,板间变异系数均<10%。

    典型数据

    由于实验操作条件的不同(如操作者、移液技术、洗板技术和稳定条件等),标准曲线的OD值会有所差异。以下数据和曲线仅供参考,实验者需根据自己的实验建立标准曲线。
