|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:||Human recombinant NGAL in monomer and dimer forms adsorbed to aluminium hydroxide gel|
|Specificity:||HYB 211-02 is specific for human NGAL, and cross-reacts with cynomolgus monkey (Macaca fascicularis) NGAL.|
|Epitope specificity:||Differs from those of HYB 211-01, ABS 038-14, -15, -23 and ABS 062-33.|
|Reactivity:||HYB 211-02 reacts strongly with human NGAL. Strong reaction is
seen when used as detection antibody in sandwich ELISA in
combination with a polyclonal NGAL capture antibody and when tested
on recombinant NGAL coated directly onto the well. HYB 211-02
reacts with NGAL in immunochemical staining of
paraformaldehyde-fixed sections containing neutrophils. In Western
blotting of SDS-PAGE gels, HYB 211-02 reacts with NGAL in both
reduced and unreduced forms. A dilution guideline of 1/50 has
proved successful (4).
HYB 211-02 (as biotinylated detection antibody) forms a sandwich pair with ABS 038-23 (as capture antibody) for measuring cynomolgus monkey (Macaca fascicularis) and human NGAL.
