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.
