Overview

产品名称: Human pNF-H(Phosphorylated Neurofilament H) ELISA Kit
反应性: Human
别名: TC2; Transcobalamin II
反应类型: Sandwich
灵敏度: 29 pg/mL
标准品: 5000 pg/mL
检测范围: 78.13-5000 pg/mL

研究领域: Neuro science
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 pNF-H. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human pNF-H. 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 pNF-H, 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 pNF-H 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pNF-H, 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) 82-97% 89%
EDTA 血浆(n=5) 93-107% 100%
Heparin 血浆(n=5) 95-107% 101%

线性

将添加有pNF-H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) 89-96% 90-98% 87-98% 86-102%
EDTA 血浆(n=5) 87-99% 99-105% 88-97% 93-103%
