Overview

产品名称: Human Anti-GM1(Anti-Ganglioside Antibody) ELISA Kit
反应性: Human
别名: anti-ganglioside (GM1) antibody (IgG)
反应类型: Sandwich
灵敏度: 0.56 ng/mL
标准品: 80 ng/mL
检测范围: 1.25-80 ng/mL
样本类型: Serum, plasma, tissue homogenates and other biological fluids
反应时长: 3.5h
研究领域: Immune molecule;
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 Anti-GM1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Anti-GM1. 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 Anti-GM1, 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 Anti-GM1 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Anti-GM1, 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) 90-105% 97%
EDTA 血浆(n=5) 80-97% 88%
Heparin 血浆(n=5) 78-92% 85%

线性

将添加有Anti-GM1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
样本类型 1:2 1:4 1:8 1:16
血清(n=5) 88-99% 86-92% 89-103% 97-105%
EDTA 血浆(n=5) 95-104% 87-96% 82-96% 89-103%
