Tissue Inhibitors of Metalloproteinases (TIMPs) comprise a family of four inhibitors known as TIMP-1, TIMP-2, TIMP-3, and TIMP-4. Each member of the TIMP family has its own distinct profile of metalloproteinase inhibition. The matrix metalloproteinases (MMPs) are a family of zinc proteases involved in the breakdown of extracellular matrix (ECM) in normal physiological processes, such as embryonic development, tissue and bone remodeling, wound healing, tissue morphogenesis, angiogenesis, and tumor metastasis. MMPs are also known to be involved in the cleavage of cell surface receptors, the release of apoptotic ligands (such as the FAS ligand), cell proliferation, differentiation, and chemokine in/activation. The normal function of MMPs must be precisely regulated by their endogenous protein inhibitors, TIMPs . TIMPs inhibit MMPs by forming 1:1, non-covalent complexes with MMPs, thereby blocking access of substrates to the MMP catalytic site. Except for inhibition of active MMPs, TIMPs also exhibit several other biochemical and physiological/biological functions such as proMMP activation, cell growth promotion, matrix binding, inhibition of angiogenesis and the induction of apoptosis. Disruption of the MMP/TIMP balance can result in serious diseases such as arthritis, cardiovascular disorders, tumor growth and metastasis. The MILLIPLEX(R) Human TIMP Panel 2 Bead kit (TIMP-1, -2, -3, -4) has been designed for tissue/cell culture samples. The Luminex(R) xMAP(R) platform uses a magnetic bead immunoassay format for ideal speed and sensitivity to quantitate multiple analytes simultaneously, dramatically improving productivity while conserving valuable sample volume. Panel Type: Cytokines/Chemokines
