中文名称：游离甲状腺素(fT4)酶联免疫吸附测定试剂盒
Price:
- 反应性： Universal
- 检测范围： 1.56-100 pg/mL
- 灵敏度： 0.94 pg/mL
| 产品应用 | ELISA |
| 检测原理 | 本试剂盒采用竞争ELISA法。用fT4抗原包被于酶标板上，实验时样品或标准品中的fT4与包被的fT4竞争生物素标记的抗fT4单抗上的结合位点，游离的成分被洗去。加入辣根过氧化物酶标记的亲和素，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，fT4浓度与OD450值之间呈反比，通过绘制标准曲线计算出样品中fT4的浓度。 |
