Assay Principle
This kit is based on a competitive ELISA detection method. The microtiter plate is pre-coated with target antigen. During the assay, the target antigen in the sample or standard competes with the immobilized target for binding sites on the biotinylated detection antibody specific to the target antigen. After incubation, excess conjugate and unbound sample or standard are removed by washing. HRP–streptavidin (SABC) is then added to each well and incubated, followed by the addition of TMB substrate solution. The enzymatic reaction is terminated by adding an acidic stop solution, and the color change is measured at 450 nm using a microplate reader. The concentration of the target antigen in the samples is determined by comparison with the standard curve and is inversely proportional to the OD450 value.

Reagent Preparation
1. Wash Buffer: Prepare the 1X Wash Buffer using distilled water according to the manual.
2. Standard: Perform gradient dilution according to the instructions in the manual.
3. Other Concentrated Reagents: Dilute the concentrated reagents using the Dilution Buffers provided in the kit to 1 X working solutions as instructed in the manual. Always use a clean pipette tip for each different solution.
Assay Procedure
This procedure is for reference only.

After the kit equilibrates to room temperature, add standard or sample to the wells and incubate.
Aspirate and wash the plate for three times.
Immediately add Biotinylated Detection Antibody Working Solution to each well and incubate.
Aspirate and wash the plate for three times
Add Streptavidin-HRP Working Solution to each well and incubate.
Add TMB Substrate Reagent to each well and incubate.
Add Stop Reagent to each well, read the plate at OD 450 nm immediately, and calculate the results.

Precision
Intra-assay Precision (Precision within an assay): CV% ≤ 10%
Intra-assay precision was evaluated by testing multiple replicates of samples within the same plate.

Inter-assay Precision (precision between assays): CV% ≤ 10%
Inter-assay precision was evaluated by testing samples across different plates.
Calculation of Results
1. Average the duplicate readings for each Standard, Control, and Sample, and subtract the mean optical density of the zero Standard.
2. Construct a standard curve by plotting the target concentration on the y-axis against absorbance on the x-axis and draw a curve through the data points.
3. Determine the sample concentration by substituting the OD450 value into the standard curve. For diluted samples, multiply the calculated value by the corresponding dilution factor.
