检测原理:	The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human GAL2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human GAL2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human GAL2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human GAL2 in the samples is then determined by comparing the OD of the samples to the standard curve.

精密度

板内精密度（测定内的精密度）：CV%<8%

三个已知浓度的样品分别在1个酶标板上测试20次，以评估分析板内精密度。

板间精密度（测定板间间精密度）：CV%<10%

三个已知浓度的样品分别在3个不同的酶标板上测试40次，以评估分析板件的精密度。

回收率

Matrices listed below were spiked with certain level of recombinant GAL2 and the recovery rates were calculated by comparing the measured value to the expected amount of GAL2 in samples.

样本类型	回收率范围	平均回收率
血清(n=5)	86-105%	96%
EDTA 血浆(n=5)	91-126%	109%
Heparin 血浆(n=5)	91-102%	97%

线性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of GAL2 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
