Human IL-8 ELISA Kit

KE00006 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The IL8 ELISA kit is to be used to detect and quantify protein levels of endogenous IL8. The assay recognizes human IL8. An antibody specific for IL8 has been pre-coated onto the microwells. The IL8 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for IL8 is added to detect the captured IL8 protein. For signal development, horseradish peroxidase (HRP)-conjugated antibody 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 450nm with the correction wavelength set at 630 nm.
