    与传统ELISA试剂盒相比,将实验时间缩短了至少1-2小时,同时提高了试剂盒的灵敏度,让客户可以获得更加精确的实验结果。该系列是Elabscience自主开发的新技术,旨在帮助客户以更为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小鼠血清、血浆或其他相关生物液体中E2浓度。

    检测原理

    本试剂盒采用竞争ELISA法。用小鼠 E2抗原包被于酶标板上,实验时加入样品(或标准品)和辣根过氧化物酶(HRP)标记的抗E2单克隆抗体,样本(或标准品中)的E2与包被抗原E2竞争结合HRP标记的抗E2单抗上的结合位点,形成包被抗原E2-HRP标记的抗E2单抗复合物,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450 nm波长处测OD值,E2浓度与OD450值之间呈反比,通过绘制标准曲线计算出样品中E2的浓度。

    反应类型 竞争法
    规格 96T
    反应时间 1.5h
    反应性 小鼠
    检测方法 Colormetric
    检测范围 3.13-200 pg/mL

    特异性

    可检测样本中的小鼠E2,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。
