测试原理:

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with MDA protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to MDA. 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 stop solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of MDA in the samples is then determined by comparing the OD of the samples to the standard curve.

技术数据

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

Concentration	OD1	OD2	Average OD
2000	0.22	0.222	0.221
1000	0.356	0.359	0.358

精密度

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level were tested on 3 different plates, 20 replicates in each plate, respectively.

回收率

The recovery of spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

样本类型	Range(%)	Average Recovery(%)
Serum (n=8)	96-107	101
EDTA plasma (n=8)	90-105	97
Cell culture media (n=8)	85-97	91

线性

Samples were spiked with high concentrations of target proteins and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
