Components	96-well polystyrene enzyme-linked immunosorbent assay (ELISA) plate coated with anti-IL-21 monoclonal antibody Human IL-21 freeze-dried standard IL-21 detect Antibody Standard Diluent HRP-labeled streptavidin Assay Buffer(10×) Substrate TMB Stop Solution Washing Buffer(20×)
Assay Principle	This kit utilizes the double antibody sandwich enzyme-linked immunosorbent assay (ELISA) detection technique.Specific anti-human IL-21 antibodies are precoated on a high-affinity ELISA plate. Standard samples, test samples, and biotinylated detection antibodies are added to the wells of the ELISA plate. After incubation, IL-21 present in the samples binds to the solid-phase antibodies and the detection antibodies. After washing to remove unbound substances, streptavidin-HRP labeled with horseradish peroxidase is added. After washing, a colorimetric substrate, TMB, is added and the plate is incubated in the dark for color development. The intensity of the color reaction is directly proportional to the concentration of IL-21 in the samples.A stop solution is added to terminate the reaction, and the absorbance value is measured at a wavelength of 450 nm (with a reference wavelength range of 570-630 nm).

Competitive ELISA: Principles, Methods, and Key Differences

Competitive ELISA is a widely used immunoassay technique for quantifying target analytes in samples by measuring their interference with a known signal. This method is based on the principle of limited antibodies, where the target analyte competes with a labeled antigen for antibody binding. Competitive ELISA is commonly used for detecting small molecules with fewer epitopes and is available in direct and indirect formats. This article explains the fundamental principles, experimental workflow, and key differences between direct and indirect competitive ELISA, helping researchers choose the optimal method for their applications.
