Overview

产品名称: Rat FPA(Fibrinopeptide A) ELISA Kit
反应性: Rat
别名: FP-A
反应类型: Competitive Inhibition
灵敏度: 0.51 ng/mL
标准品: 100 ng/mL
检测范围: 1.57-100 ng/mL

研究领域: Signal transduction;Hematology;
检测原理: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Rat FPA. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat FPA. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. 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 Rat FPA 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FPA， 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) 85-97% 91%
EDTA 血浆(n=5) 95-107% 101%
Heparin 血浆(n=5) 82-95% 87%

线性

将添加有FPA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) 85-92% 79-96% 87-103% 95-102%
EDTA 血浆(n=5) 78-96% 89-102% 85-97% 79-97%
Heparin 血浆(n=5) 87-94% 91-103% 82-99% 99-104%
