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 AP12. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human AP12. 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 AP12 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AP12, 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) 80-95% 87%
EDTA 血浆(n=5) 85-98% 91%
Heparin 血浆(n=5) 96-107% 102%

线性

将添加有AP12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) 85-104% 97-106% 86-97% 92-99%
EDTA 血浆(n=5) 85-93% 87-96% 79-91% 95-103%
