This kit is based on a double-antigen sandwich enzyme-linked immunosorbent assay (ELISA) detection method for the quantitative measurement of Human FliC (Flagellin protein) in the following samples: Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate, Other Liquid Samples. The microplate provided in this kit has been pre-coated with a specific antigen. Standards and appropriately diluted samples are added to the wells and incubated, allowing target antibodies in the sample to bind to the immobilized antigen. After incubation and washing to remove unbound components, a biotin-labeled antigen is added, forming a sandwich complex. HRP-conjugated Streptavidin is then added, followed by TMB substrate solution to produce a colorimetric reaction. The reaction is stopped with an acidic solution, and absorbance is measured at 450 nm using a microplate reader. The signal intensity is directly proportional to the concentration of the target analyte and is determined using a standard curve.

Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
Step
Procedure
1
Reagent & Plate Preparation: Equilibrate TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
