Lablisa® Mouse IFABP/FABP2(Intestinal Fatty Acid Binding Protein) ELISA Kit
Product Information
- Description
- More Infomation
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse IFABP/FABP2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse IFABP/FABP2. 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 Mouse IFABP/FABP2, 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 Mouse IFABP/FABP2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Precision
Intra-assay Precision (Precision within an assay)：CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays)：CV%<10%
Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
Recovery
Matrices listed below were spiked with certain level of recombinant IFABP/FABP2 and the recovery rates were calculated by comparing the measured value to the expected amount of IFABP/FABP2 in samples.
| Matrix | Recovery range | Average |
|---|---|---|
| serum(n=5) | 96-109% | 102% |
| EDTA plasma(n=5) | 81-95% | 88% |
| Heparin plasma(n=5) | 85-97% | 91% |
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of IFABP/FABP2 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Matrix | 1:2 | 1:4 | 1:8 | 1:16 |
|---|---|---|---|---|
| serum(n=5) | 86-97% | 83-96% | 91-103% | 96-105% |
| EDTA plasma(n=5) | 95-102% | 98-106% | 87-98% | 91-102% |
| Heparin plasma(n=5) | 89-99% | 88-104% | 84-98% | 95-105% |
