MS为Mini Sample的缩写。MS系列试剂盒的上样量仅为传统夹心法ELISA试剂盒的1/4,能有效解决实验样本体积不够的问题。Elabscience®自主开发的新技术,旨在帮助您以更高效的方式进行科学研究。
用途
该试剂盒用于体外定量检测Mouse 血清,血浆或其他生物体液中IL-6浓度
检测原理
本试剂盒采用双抗体夹心ELISA法。用抗小鼠IL-6抗体包被于酶标板上,实验时样品或标准品中的小鼠IL-6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小鼠IL-6抗体和辣根过氧化物酶标记的亲和素。抗小鼠IL-6抗体与结合在包被抗体上的小鼠IL-6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,IL-6浓度与OD450值之间呈正比,通过绘制标准曲线计算出样品中IL-6的浓度。
