- Assay Procedure Summary
-
- Step 1: Add 100ul standard or sample into each well, seal the plate and statically incubate for 90 minutes at 37°C.
- Washing: Wash the plate twice without immersing.
- Step 2: Add 100ul biotin-antibody working solution, seal the plate and statically incubate for 60 minutes at 37°C.
- Washing: Wash the plate three times and immerse for 1min each time.
- Step 3: Add 100ul HRP-Streptavidin Conjugate (SABC) working solution, seal the plate and statically incubate for 30 minutes at 37°C.
- Washing: Wash the plate five times and immerse for 1min each time.
- Step 4: Add 90ul TMB substrate solution, seal the plate and statically incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)
- Step 5: Add 50ul stop solution. Read at 450nm immediately and calculate.
- Standard Curve
-
This product is detected by QC department and meets performance required in the manual. (Laboratory Humidity: 20%-60%; Temperature: 18°C -25°C; Equilibrate TMB substrate to 37°C before staining. After adding into the ELISA wells, incubate for 15min at 37°C in dark.)
Due to different assay environments and operations, assay data below and standard curve are provided for reference. Experimenters should establish standard curve according to their own assay.

- Recovery
-
Add a certain amount of IL-8 into the sample. Calculate the recovery by comparing the measured value with the expected amount of IL-8 in the sample.
Sample Type | Recovery Range(%) | Average(%) |
serum(n=10) | 85-105 | 97 |
EDTA plasma(n=10) | 89-105 | 95 |
Heparin plasma(n=10) | 95-103 | 100 |
- Linearity
-
Dilute the sample with a certain amount of IL-8 at 1:2, 1:4 and 1:8 to get the recovery range.
Sample Type | 1:2 | 1:4 | 1:8 |
serum(n=10) | 90-100% | 85-98% | 92-104% |
EDTA plasma(n=10) | 90-100% | 90-99% | 82-101% |
Heparin plasma(n=10) | 81-95% | 83-97% | 81-99% |
- Precision(%)
-
Intra-assay Precision: samples with low, medium and high concentration are tested 20 times on the same plate.
Inter-assay Precision: samples with low, medium and high concentration are tested 20 times on three different plates.
