Product Information
KE00298 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The MMP-9 ELISA kit is to be used to detect and quantify protein levels of endogenous MMP-9. The assay recognizes human MMP-9. An antibody specific for MMP-9 has been pre-coated onto the microwells. The MMP-9 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for MMP-9 is added to detect the captured MMP-9 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 450 nm with the correction wavelength set at 630 nm.

Background Information
MMP9 (matrix metallopeptidase 9), also named as Gelatinase B, is a member of matrix metalloproteinase (MMP) family. The MMP family of enzymes is comprised of critically important extracellular matrix remodeling proteases whose activity has been implicated in normal embryogenesis, tissue remodelling and many diseases such as arthritis, cancer, periodontitis, glomerulonephritis, encephalomyelitis, atherosclerosis and tissue ulceration. These proteases have come to represent important therapeutic and diagnostic targets for the treatment and detection of human cancers. MMP9 is produced by a variety of normal and transformed cells including neutrophils, monocytes, macrophages, astrocytes, fbroblasts, osteoclasts and so on. In tumors, MMP-9 destroys collagen (type IV) in the vascular basal membrane in the vicinity of tumor cells which invade the surrounding tissues and contributes to metastasis. Circulating levels of MMP-9 are increased in many inflammatory disorders such as atherosclerosis, hepatitis C virus infection and colorectal cancer.
