Lablisa® LTA4(Leukotriene A4) ELISA Kit
Product Information
- Description
- More Infomation
This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with LTA4. Standards or samples are added to the appropriate micro ELISA plate wells then with a biotin-conjugated antibody specific to LTA4. 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 LTA4 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): 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.
Recovery
The recovery of spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
| Matrix | Recovery range | Average |
|---|---|---|
| serum(n=8) | 82-95% | 88% |
| EDTA plasma(n=8) | 88-102% | 95% |
| Cell culture media (n=8) | 95-107% | 101% |
Linearity
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.
| Matrix | 1:2 | 1:4 | 1:8 | 1:16 |
|---|---|---|---|---|
| serum(n=5) | 95-103% | 80-96% | 87-98% | 85-92% |
| EDTA plasma(n=5) | 80-95% | 80-95% | 96-103% | 83-101% |
| Cell culture media (n=5) | 82-97% | 88-105% | 80-93% | 87-98% |
