KE00149 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The CCL20 ELISA kit is to be used to detect and quantify protein levels of endogenous CCL20. The assay recognizes human CCL20. An antibody specific for CCL20 has been pre-coated onto the microwells. The CCL20 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human CCL20 is added to detect the captured human CCL20 protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.
