SILu™Lite ALB Albumin human
SIGMA/MSST0012 - recombinant, expressed in HEK 293 cells, MS Protein Standard
Synonym: Albumin; Mass spectrometry standard, Human Albumin
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
Human serum albumin is a ~69 kDa predominantly monomeric protein with one free sulfhydryl group and 17 intrachain disulfide bonds.

| Biochem/physiol Actions: | Albumin is synthesized exclusively by the liver parenchymal cells at a rate of 14 g/day. While it is the most abundant plasma protein (>50%), increased urine albumin concentrations indicate bleedings in the lower urinary tract (ureter, bladder) or infections of the renal pelvis. A small abnormal albumin excretion is known as Microalbuminuria and serves as an indicator for temporary overload of the glomerular filtration (fever, excessive sports) or chronic injury of the glomeruli (diabetes). |
| General description: | SILu™Lite ALB is a recombinant human protein expressed in human 293 cells. It is a monomer of 607 amino acids (including C-terminal polyhistidine and flag tags), with a molecular weight of ~69 kDa. SILu™Lite ALB is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications. |
