COMPONENTS	96-well polystyrene enzyme-linked immunosorbent assay (ELISA) plate coated with anti-CD19 monoclonal antibody Human CD19 freeze-dried standard CD19 detect Antibody Standard Diluent 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 CD19 antibodies are precoated on a high-affinity ELISA plate. Standard samples, test samples, and the detection antibody labeled with horseradish peroxidase are added to the wells of the ELISA plate. After incubation, CD19 present in the samples binds to the solid-phase antibody and the detection antibody. 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 CD19 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).
