Description

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.

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).
