Overview

产品名称: Human AP13(Apelin 13) ELISA Kit
反应性: Human
别名: APLN13
反应类型: Competitive Inhibition
灵敏度: 0.21 ng/mL
标准品: 50 ng/mL
检测范围: 0.78-50 ng/mL
样本类型: Serum, plasma and other biological fluids
反应时长: 2h
研究领域: Metabolic pathway;Endocrinology;Cardiovascular biology;Neuro science;Gastroenterology;
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 Human AP13. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human AP13. 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 Human AP13 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AP13, 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) 77-95% 86%
EDTA 血浆(n=5) 92-106% 99%
Heparin 血浆(n=5) 88-103% 95%

线性

将添加有AP13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) 85-94% 87-96% 95-103% 85-91%
EDTA 血浆(n=5) 85-92% 90-96% 95-102% 87-98%
Heparin 血浆(n=5) 93-102% 90-99% 95-106% 87-101%
