Overview

产品名称: Human AMA-M2(Anti-Mitochondrial Antibody M2 Subtype) ELISA Kit
反应性: Human
别名: AMA-M2
反应类型: Sandwich
灵敏度: 0.13 ng/mL
标准品: 20 ng/mL
检测范围: 0.32-20 ng/mL

研究领域: Infection immunity;
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 AMA-M2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human AMA-M2. 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 AMA-M2, 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 AMA-M2 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,以评估分析板间的精密度。

回收率

分别往不同样本中添加已知浓度的AMA-M2, 做回收率实验,得出回收率范围和平均回收率
样本类型 回收率范围 平均回收率
血清(n=5) 87-99% 93%
EDTA 血浆(n=5) 85-97% 91%
Heparin 血浆(n=5) 82-95% 88%

线性

将添加有AMA-M2的样本分别稀释2倍,4倍,8倍,16倍做回收实验,得出回收率范围
