Assay Principle

The H. Pylori ELISA Assay Kit employs the qualitative enzyme immunoassay technique. Helicobacter antigen has been pre-coated onto a microtiter plate. Standards or samples are pipetted into the wells and any Ab present is bound by the immobilized antigen. After washing away any unbound substances, a HRP-conjugated anti human antibody is added to each well and incubate. After washing away any unbound antibody-enzyme reagent, a substrate solution (TMB) is added to the wells and color develops in proportion to the amount of Ab bound in the initial step. The color development is stopped by the addition of acid and the intensity of the color is measured at a wavelength of 450 nm ±2 nm. The concentration of Ab in the sample is then determined by comparing the O.D of samples to the standard curve.

Assay Procedure

  1. Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal it.
  2. Add 100 μl of diluted samples, Calibrators and controls into wells. Leave one well empty for the substrate blank.
  3. Incubate for 60 minutes at RT.
  4. Aspirate each well and wash, repeating the process 2 times for a total 3 washes. Wash by filling each well with 1× Wash Buffer (350 μl) using a squirt bottle, manifold dispenser, or autowasher. Complete removal of liquid at each is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating, decanting or blotting against clean paper towels.
  5. Add 100 μl 1X Antibody solution into each well (expect the substrate blank). Incubate for 30 minutes at RT.
  6. Wash as according to step 4.
  7. Add 100 μl of TMB Reagent to each well. Incubate for 20 minutes at room temperature.
  8. Add 100 μl of Stop Solution to each well.
  9. Read the OD with a microplate reader at 450 nm immediately.
