|Antigen:||Neutrophil gelatinase-associated lipocalin (NGAL; also called lipocalin 2, siderocalin and neutrophil lipocalin) is a member of the lipocalin family of proteins which bind and transport small lipophilic molecules. NGAL is released by activated neutrophils and occurs as 25-kDa glycosylated single protein chain monomers, which form dimers and small amounts of higher oligomers, as well as complexes with matrix metalloproteinase 9 (MMP-9; gelatinase B) (1). Low level expression of NGAL in a variety of epithelia may be increased in inflammation or cancers (2). Expression of NGAL in the kidney is dramatically increased by acute kidney injury (3).|
|Immunogen:||Recombinant human NGAL adsorbed onto aluminum hydroxide gel|
|Specificity:||ABS 038-15 binds human NGAL and does not cross-react with NGAL from other mammalian species tested|
|Epitope specificity:||Differs from those of HYB 211, ABS 038 and the ABS 062 series of antibodies.|
|Reactivity:||ABS 038-15 binds human NGAL in solution and coated onto a solid phase. ABS 038-15 (as capture antibody) forms sandwich pairs with HYB 211-02, ABS 038-04, ABS 038-14, ABS 038-23 and ABS 038-26 (as biotinylated detection antibodies) for measuring human NGAL. When ABS 038-15 is used as biotinylated detection antibody with ABS 038-14 as capture antibody, the assay reacts equally with NGAL monomer and homodimer on a mass basis.|
