KE00065 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The MCAM ELISA kit is to be used to detect and quantify protein levels of endogenous MCAM. The assay recognizes human MCAM. A monoclonal antibody specific for MCAM has been pre-coated onto the microwells. The MCAM protein in samples is captured by the coated antibody after incubation. Following extensive washing, a polyclonal antibody specific for MCAM is added to detect the captured MCAM 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.
