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). The expression and release of NGAL from renal tubules are dramatically increased by ischemic or nephrotoxic injury (3).

HYB 211-01 is specific for human NGAL. No cross-reaction with NGAL from other species has been detected

Epitope specificity differs from that of HYB 211-02 and HYB 211-05.

HYB 211-01 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 211-01 reacts with NGAL in immunochemical staining of paraformaldehyde-fixed sections containing neutrophils. In Western blotting of SDS-PAGE gels, HYB 211-01 reacts with NGAL in both reduced and unreduced forms (4).
