COMPONENTS	96-well polystyrene enzyme-linked immunosorbent assay (ELISA) plate coated with anti-CHI3L1 monoclonal antibody Human CHI3L1 freeze-dried standard CHI3L1 detect Antibody HRP-labeled streptavidin Assay Buffer(10×) Substrate TMB Stop Solution Washing Buffer(20×) Sealing Film
ASSAY PRINCIPLE	This kit utilizes the double antibody sandwich enzyme-linked immunosorbent assay (ELISA) detection technique.Specific anti-human CHI3L1 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, CHI3L1 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, the TMB chromogenic substrate is added, and color development is carried out while avoiding light. The intensity of the color reaction is directly proportional to the concentration of CHI3L1 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).
