| Application: | This ELISA kit applies to the in vitro quantitative determination of Rat CD8 concentrations in serum, plasma and other biological fluids. |
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 Rat CD8. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat CD8 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 Rat CD8, 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 Rat CD8. You can calculate the concentration of Rat CD8 in the samples 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 Rat CD8 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat CD8 were tested on 3 different plates, 20 replicates in each plate.

Recovery
The recovery of Rat CD8 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
| Sample Type | Range (%) | Average Recovery (%) |
| Serum(n=8) | 85-98 | 91 |
| EDTA plasma (n=8) | 88-99 | 94 |
| Cell culture media (n=8) | 93-104 | 98 |
| 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 100μL standard or sample to the wells. Incubate for 90 min at 37°C |
| 2. | Discard the liquid, immediately add 100μL Biotinylated Detection Ab working solution to each well. Incubate for 60 min at 37°C |
| 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 |
