SIGMA/MSST0030 - recombinant, expressed in HEK 293 cells, MS Protein Standard
Synonym: Apo-AII human; ApoA-II; ApoA-II; ApolipoproteinA2
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: | SILu™Lite APOA2 is a recombinant human protein expressed in human 293 cells. It is a homodimer consisting of 97 amino acids (including C-terminal polyhistidine and flag tags), with a calculated molecular mass of 11 kDa. SILu Lite APOA2 is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications. |
| General description: | Apolipoprotein A-II (ApoA-II) occurs in plasma as a dimer of two 77-amino acid chains linked by a disulfide bridge. After apoA-I, it is the second major protein component of HDL, accounting for approximately 20% of HDL total protein. ApoA-II is thought to play an important role in triglyceride metabolism both from animal and human studies. 3 Recent findings attribute apoA-II to inhibitory effects on lipoprotein lipase-mediated hydrolysis of triglyceride-rich particles. Additional associations of apoA-II have been reported for a variety of protein factors including hepatic lipase (HL), lipoprotein lipase (LPL), endothelial lipase, CETP, PLTP, and LCAT. |
