中文名称:人防御素β2(DEFβ2/DEFB2)酶联免疫吸附测定试剂盒

Price:
- 反应性: Human
- 检测范围: 62.5-4000 pg/mL
- 灵敏度: 37.5 pg/mL
产品应用 | ELISA |
检测原理 | 本试剂盒采用双抗体夹心ELISA法。用抗人DEFβ2/DEFB2抗体包被于酶标板上,实验时样品(或标准品)中的人DEFβ2/DEFB2会与包被抗体结合。后依次加入生物素化的抗人DEFβ2/DEFB2抗体和辣根过氧化物酶标记的亲和素,抗人DEFβ2/DEFB2抗体与结合在包被抗体上的人DEFβ2/DEFB2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450 nm波长处测OD值,DEFβ2/DEFB2浓度与OD450值之间呈正比,通过绘制标准曲线计算出样品中DEFβ2/DEFB2的浓度。 |
