Step
Procedure
1
Reagent & Plate Preparation: Equilibrate reagents and TMB substrate to room temperature. Set standard, test sample and control (zero) wells on the pre-coated plate and record their positions.
2
Primary Incubation: Prepare standards, samples, blanks and load into designated wells. Incubate plate at 37°C for 90 minutes to allow antigen binding.
3
Detection Antibody Binding: Add biotin-labeled detection antibody and incubate at 37°C for 60 minutes.
4
HRP-Streptavidin Binding: Add HRP-Streptavidin (SABC) and incubate at 37°C for 30 minutes.
5
Color Development: Add TMB substrate and incubate in the dark for 10–20 minutes.
6
Stop Reaction & Reading: Add stop solution and measure absorbance at 450 nm immediately.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant supernatant and store appropriately.
Plasma
Collect using anticoagulant tubes, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Tissue Homogenate
