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 TC into the sample. Calculate the recovery by comparing the measured value with the expected amount of TC in the sample.
Matrix Recovery range(%) Average(%)
serum(n=10) 85-105 97
EDTA plasma(n=10) 94-104 99
Heparin plasma(n=10) 86-105 99
Linearity: Dilute the sample with a certain amount of TC at 1:2, 1:4 and 1:8 to get the recovery range.

Step 1: Wash the plate twice before adding the standard and sample.
Step 2: Add 50ul standard or sample into each well. Immediately add 50ul biotin-labeled antibody working solution into each well (The tip can't be reused after touching the liquid.), gently shake the plate for 1min, seal closely and statically incubate for 45 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 into each well, 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.
