QuicKey Pro系列
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人血清、血浆或其他相关生物液体中CRP浓度。
检测原理
本试剂盒采用双抗体夹心ELISA法。用抗人 CRP抗体包被于酶标板上,实验时加入样品(或标准品)和辣根过氧化物酶(HRP)标记的抗CRP检测抗体,样本(或标准品中)的CRP与包被抗体CRP及HRP标记的抗CRP抗体结合,形成包被抗体-CRP-HRP标记的抗CRP抗体的复合物,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,CRP浓度与OD450值之间呈正比,通过绘制标准曲线计算出样品中CRP的浓度。
