  • 用途

    该试剂盒用于体外定量检测大鼠serum, plasma and other biological fluids中Aβ1-42浓度

    检测原理

    本试剂盒采用双抗体夹心ELISA法。用抗大鼠Aβ1-42抗体包被于酶标板上,实验时样品或标准品中的大鼠Aβ1-42会与包被抗体结合,游离的成分被洗去。依次加入生物素化的抗大鼠Aβ1-42抗体和辣根过氧化物酶标记的亲和素。抗大鼠Aβ1-42抗体与结合在包被抗体上的大鼠Aβ1-42结合、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,Aβ1-42浓度与OD450值之间呈正比,通过绘制标准曲线计算出样品中Aβ1-42的浓度。
