SILu™Prot AMBP Alpha-1 Microglycoprotein human
SIGMA/MSST0013 - recombinant, expressed in HEK 293 cells, SIL MS Protein Standard, 13C and 15N-labeled
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, with approximately half of the circulating protein complexed to IgA. The free form is readily 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). |
| General description: | SILu™ Prot AMBP is a recombinant, stable isotope-labeled human AMBP 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 AMBP in mass-spectrometry. SILu™ Prot AMBP is a monomer of 204 amino acids (including C-terminal polyhistidine and flag tags), with a molecular weight of ~23 kDa. |
