This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with IgG4. During the reaction, IgG4 in the sample or standard competes with a fixed amount of IgG4 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to IgG4. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of IgG4 in tested samples can be calculated by comparing the OD of the samples to the standard curve.
| Kit Components: | An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the components separately according to the following conditions once the kit is received.
|
| 1. | Add 50μL standard or sample to the wells, immediately add 50μL Biotinylated Detection Ab working solution to each well. Incubate for 45 min at 37°C |
| 2. | Aspirate and wash the plate for 3 times |
| 3. | Add 100μL HRP conjugate working solution. Incubate for 30 min at 37°C. Aspirate and wash the plate for 5 times |
| 4. | Add 90μL Substrate Reagent. Incubate for 15 min at 37°C |
| 5. | Add 50μL Stop Solution |
| 6. | Read the plate at 450nm immediately. Calculation of the results |
