Test Principle
This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Universal TGF-β1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Universal TGF-β1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Universal TGF-β1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Universal TGF-β1. You can calculate the concentration of Universal TGF-β1 in the samples by comparing the OD of the samples to the standard curve.

Technical Data:
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and
high level Human TGF-β1 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and
high level Human TGF-β1 were tested on 3 different plates, 20 replicates in each plate,
respectively.

 |
3. Aspirate and wash the plate for 3 times |
 |
4. Add 100μL HRP conjugate working solution. Incubate for 30 min at 37°C. Aspirate and wash the plate for 5 times |
 |
5. Add 90μL Substrate Reagent. Incubate for 15 min at 37°C |
 |
6. Add 50μL Stop Solution |
 |
7. Read the plate at 450nm immediately. Calculation of the results |
