SILu™Lite AMBP Alpha-1 Microglycoprotein human
SIGMA/MSST0014 - recombinant, expressed in HEK 293 cells, MS protein standard
Synonym: Alpha-
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: | AMBP is synthesized by the liver. Approximately half of the circulating protein is complexed to IgA. The free form of AMBP is filtered by the glomerulus and reabsorbed by proximal tubule cells. AMBP has been found to be a sensitive biomarker for proximal tubular dysfunction even in the early phase of injury when no histologic damage is observable. In addition, urinary AMBP has been proposed to be a useful marker of tubular dysfunction even in low-gestational-age preterm infants, a population at high risk for AKI (Acute Kidney Injury). Urinary AMBP is also a marker of kidney damage in type 2 diabetes. |
| General description: | SILu™ Lite AMBP is a recombinant human protein expressed in human 293 cells. It is a monomer of 204 amino acids (including C-terminal polyhistidine and flag tags), with a molecular weight of ~23 kDa. SILu™ Lite AMBP is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications. |
