Other materials and equipment required:

  • Microplate reader (wavelength: 450nm)
  • 37°C incubator (CO2 incubator for cell culture is not recommended.)
  • Automated plate washer or multi-channel pipette/5ml pipettor (for manual washing purpose)
  • Precision single (0.5-10μL, 5-50μL, 20-200μL, 200-1000μL) and multi-channel pipette with disposable tips(Calibration is required before use.)
  • Sterile tubes and Eppendorf tubes with disposable tips
  • Absorbent paper and loading slot
  • Deionized or distilled water
Recovery: Add a certain amount of TNFα into the sample. Calculate the recovery by comparing the measured value with the expected amount of TNFα in the sample.
Matrix Recovery range(%) Average(%)
serum(n=5) 86-100 94
EDTA plasma(n=5) 85-104 90
Heparin plasma(n=5) 89-101 96
Linearity: Dilute the sample with a certain amount of TNFα at 1:2, 1:4 and 1:8 to get the recovery range.
Sample 1:2 1:4 1:8
serum(n=5) 88-105% 85-95% 91-100%
EDTA plasma(n=5) 85-97% 86-99% 86-98%
Heparin plasma(n=5) 97-104% 90-97% 87-100%
Stability: Perform the stability test for the sealed kit at 37°C and 2-8°C and get relevant data.

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.
