SILu™Prot TIMP2, Metalloproteinase inhibitor 2 human
SIGMA/MSST0045 - recombinant, expressed in HEK 293 cells, SIL MS Protein Standard, 13C and 15N-labeled
Product Type: Chemical
SILuProt products are stable isotope-labeled full length proteins designed to be used as mass spectrometry internal standards for quantitative proteomics. Introduction of an internal SILuProt standard at the beginning of the MS workflow minimizes variations in quantification due to protein extraction, fractionation, enrichment, proteolysis and analysis

| 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. |
| General description: | SILu™Prot TIMP2 is a recombinant, stable isotope-labeled human TIMP2 which incorporates [13C6, 15N4]-Arginine and [13C6, 15N2]-Lysine. Expressed in human 293 cells, it is designed to be used as an internal standard for bioanalysis of TIMP2 in mass-spectrometry. SILu™Prot TIMP2 is a protein of 194 amino acids , with a calculated molecular mass of 21.7 kDa. |
