Overview

产品名称: Rat 6ketoPGF1α(6-keto-PGF1 alpha) ELISA Kit
反应性: Rat
别名: 6-keto-PGF1 alpha; 6ketoPGF1α
反应类型: Competitive Inhibition
灵敏度: 1.4 pg/mL

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 6ketoPGF1α. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat 6ketoPGF1α. 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 6ketoPGF1α 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6ketoPGF1α, 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) 90-103% 86%

线性

将添加有6ketoPGF1α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
