Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate TIMP2 in samples. An antibody specific for TIMP2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTIMP2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TIMP2 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 TIMP2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:TIMP2, is a member of the TIMP family. The proteins are natural inhibitors of the matrix metalloproteinases, a group of peptidases involved in degradation of the extracellular matrix. In addition to an inhibitory role against metalloproteinases, the encoded protein has a unique role among TIMP family members in its ability to directly suppress the proliferation of endothelial cells. As a result, the encoded protein may be critical to the maintenance of tissue homeostasis by suppressing the proliferation of quiescent tissues in response to angiogenic factors, and by inhibiting protease activity in tissues undergoing remodelling of the extracellular matrix. In melanocytic cells TIMP2 gene expression may be regulated by MITF.
