No significant cross-reactivity or interference between Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1) and analogues was observed.

Recovery

Matrices listed below were spiked with certain level of recombinant Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1) and the recovery rates were calculated by comparing the measured value to the expected 黏膜地址素细胞黏附分子(MAdCAM1)检测试剂盒amount of Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1) in samples.

Matrix     Recovery range (%)     Average(%)    

serum(n=5)     93-101     97    

EDTA plasma(n=5)     97-105     101    

heparin plasma(n=5)     90-104     93    

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Linearity

The linearity of the kit was 黏膜地址素细胞黏附分子(MAdCAM1)检测试剂盒assayed by testing samples spiked with appropriate concentration of Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample     1:2     1:4     1:8     1:16    

serum(n=5)     84-101%     81-98%     94-101%     80-103%    

EDTA plasma(n=5)     94-101%     98-105%     96-103%     90-99%    

heparin plasma(n=5)     81-93%     95-103%     96-104%     87-102%    

Stability

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested 黏膜地址素细胞黏附分子(MAdCAM1)检测试剂盒that the whole assay is performed by the same operator from the beginning to the end.

Test principle

The test principle applied黏膜地址素细胞黏附分子(MAdCAM1)检测试剂盒 in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mucosal Addressin Cell Adhesion Molecule 1 (MAdCAM1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 Mucosal Addressin Cell Adhesion 黏膜地址素细胞黏附分子(MAdCAM1)检测试剂盒Molecule 1 (MAdCAM1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
