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: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 ELN into the sample. Calculate the recovery by comparing the measured value with the expected amount of ELN in the sample.

Sample Type	Recovery Range(%)	Average(%)
serum(n=10)	92-105	99
EDTA plasma(n=10)	87-105	96
Heparin plasma(n=10)	87-102	95

Linearity

Dilute the sample with a certain amount of ELN at 1:2, 1:4 and 1:8 to get the recovery range.

Sample Type	1:2	1:4	1:8
serum(n=10)	89-102%	85-102%	86-99%
EDTA plasma(n=10)	87-100%	85-99%	86-99%
Heparin plasma(n=10)	82-90%	85-93%	81-100%

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.
