General description
SILu™Prot ALB is a recombinant, stable isotope-labeled human albumin 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 albumin in mass-spectrometry. SILu™Prot ALB is a monomer of 607 amino acids (including C-terminal polyhistidine and flag tags), with a molecular weight of ~69 kDa.
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).
Physical form
Supplied as a lyophilized powder containing phosphate buffered saline.
