◤反应原理(Test Principle)：
本试剂盒采用竞争ELISA法。用fT3抗原包被于酶标板上，实验时样品或标准品中的fT3与包被的fT3竞争生物素标记的抗fT3单抗上的结合位点，游离的成分被洗去。加入HRP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HRP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，fT3浓度与OD450值之间呈反比，通过绘制标准曲线计算出样品中fT3的浓度。
◤存储(Storage)：

| ◤典型数据(Typical Data): | |
 | fT3 ELISA Standard Curve Typical data are for reference only and curves should be replotted for each experiment. The Logistics function is recommended for fitting. |
◤精密度(Precision):
| ||||||||||||||||||||||||||||||||||||||||||
Intra-assay precision (intra-assay precision): Low, medium, and high levels of fT3 were measured on a single plate 20 times at each level. Inter-assay Precision (interassay precision): Samples containing low, intermediate, and high levels of fT3 were assayed 20 times per plate on 3 different plates. | ||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||
◤回收率(Recovery):
| ||||||||||||
| Three different levels of fT3 spiked in samples were evaluated for recovery in different matrices. | ||||||||||||
|
◤线性(Linearity):
|
| A high concentration of fT3 is added to the sample, which is then diluted with a standard and a sample diluent to bring the value of the sample within the detection range. |
