General description
SILu™Lite TIMP2 is a recombinant human protein expressed in human 293 cells. It consists of 194 amino acids, with a calculated molecular mass of 21.7 kDa. SILu™Lite TIMP2 is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications.
Biochem/physiol Actions
While the mammalian TIMP family has four members, TIMP-2 is a unique family member in that in addition to inhibiting matrix metalloproteinases (MMPs), TIMP-2 selectively interacts with MT1-MMP to facilitate the cell-surface activation of pro-MMP-2.1 Thus, TIMP-2 functions both as an inhibitor of MMPs, and is required for the cellular mechanism of pro-MMP-2 activation. Recently, it was validated that combination of TIMP-2 with another urinary cell-cycle arrest biomarkers, i.e. the insulin-like growth factor-binding protein 7 (IGFBP7) may predict the risk of moderate and severe acute kidney injury (AKI) in critically ill patients. For postoperative surgical intensive care unit patients, a single urinary TIMP2•IGFBP7 test accurately identified patients at risk for developing AKI within the ensuing 12 hours and its inclusion in clinical risk prediction models significantly enhances their performance.
Physical form
Supplied as a lyophilized powder containing phosphate buffered saline.
