Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate MMP13 in samples. An antibody specific for MMP13 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMMP13 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for MMP13 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of MMP13 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:MMP-13 has been proposed to participate in aggrecan degradation associated with osteoarthritis and cleavage of type II collagen in osteoarthritic cartilage explants and in tumor progression and metastasis . In addition, it can cleave type I, III, IV, IX, X and XIV collagens and fibronectin. MMP-13 is likely to play a crucial role in the modulation of extracellular matrix degradation and cell-matrix interactions .MMP-13 is expressed by several metastatic tumors including breast carcinomas, chondrosarcomas, head and neck carcinomas, and in degenerative bone diseases including rheumatoid arthritis. Wild type and mutant p53, a tumor suppressor gene, differentially regulate MMP-13 gene expression . Members of the activator protein-1 and core-binding factor families increase MMP-13 promoter activity in normal, differentiating osteoblasts .
