Required Instruments and Reagents

1. Microplate reader (wavelength: 450nm)
2. 37°C incubator (CO2 incubator for cell culture is not recommenced.)
3. Automated plate washer or multi-channel pipette/5ml pipettor (for manual washing purpose)
4. Precision single (0.5-10μL, 5-50μL, 20-200μL, 200-1000μL) and multi-channel pipette with disposable tips(Calibration is required before use.)
5. Sterile tubes and Eppendorf tubes with disposable tips
6. Absorbent paper and loading slot
7. Deionized or distilled water

Assay Procedure Summary

• Step 1: Take out the required plate wells, add 50ul Cap/Det Ab into each well, then add 50ul Standard or Sample into individual well. (When adding standard or sample, the disposable tip lightly touches the liquid level. Change the disposable tips for different samples and standards.) Gently tap the plate for 10s to ensure thorough mixing then static incubate for 60 minutes at 37°C.
• Washing: Wash the plate twice without immersion.
• Step 2: Add 100ul HRP-Streptavidin (orange) into each well, seal the plate and static incubate for 30 minutes at 37°C.
• Washing: Wash the plate five times without immersion.
• Step 3: Add 90ul TMB substrate solution, seal the plate and static incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)
• Step 4: Add 50ul stop solution. Read at 450nm immediately and calculate.

Standard CurveThis 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.

RecoveryAdd a certain amount of IL-17 into the sample. Calculate the recovery by comparing the measured value with the expected amount of IL-17 in the sample.

Sample Type	Recovery Range(%)	Average(%)
serum(n=10)	91-104	94
EDTA plasma(n=10)	85-103	98
Heparin plasma(n=10)	86-105	98

LinearityDilute the sample with a certain amount of IL-17 at 1:2, 1:4 and 1:8 to get the recovery range.

Sample Type	1:2	1:4	1:8
serum(n=10)	91-101%	88-101%	86-99%
EDTA plasma(n=10)	82-100%	85-98%	85-100%
Heparin plasma(n=10)	85-100%	89-96%	85-100%

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.
