SILu™Lite CLU Clusterin human
SIGMA/MSST0008 - recombinant, expressed in HEK 293 cells, MS Protein Standard
Synonym: Apolipoprotein J; Clusterin; Testosterone-
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: | Clusterin is a secreted glycosylated, 80-kDa disulfide-linked heterodimer of alpha and beta subunits (produced by internal cleavage). Clusterin is expressed in virtually all tissues and found in all human fluids. It is involved in numerous physiological processes important for carcinogenesis and tumor growth, including anti-apoptotic cell survival, cell cycle regulation, cell adhesion, tissue remodeling and lipid transportation. Clusterin also exists as a nuclear protein. The secreted form of Clusterin has extracellular chaperone and anti-apoptotic activities while the nuclear form acts as a proapoptotic factor. |
| General description: | SILu™Lite Clusterin is a recombinant human protein expressed in human 293 cells. It is a heterodimer of 2 subunits (alpha and beta) consisting of 427 amino acids (including N-terminal polyhistidine and V5 tags), with a calculated molecular weight of 50 kDa. SILu™Lite Clusterin is designed to be used as an internal standard for bioanalysis of Clusterin in mass-spectrometry. |
