Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate LCN2 in samples. An antibody specific for LCN2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLCN2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LCN2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LCN2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:NGAL (neutrophil gelatinase-associated lipocalin) belongs to the lipocalin family of proteins. These are typically small secreted proteins characterized by their ability to bind small, hydrophobic molecules in a structurally conserved pocket formed by beta-pleated sheet, to bind to specific cell-surface receptors and to form macromolecular complexes. NGAL has many synonyms: it also known as NL (neutrophil lipocalin,HNL, rat NL), lipocalin, oncogene protein 24p3 or uterocalin (in the mouse) and neu-related lipocalin or 25 kDa alpha 2-microglobulin-related protein6 (in the rat). Rat NGAL consists of a single disulfide-bridged polypeptide chain of 178 amino-acid residues with a calculated molecular mass of 22 kDa, but glycosylation increases its apparent molecular mass to 25 kDa.
