NGAL
NGAL Recombinant Human NGAL (PHP302) was analyzed under reducing denaturing conditions (Lane 2). The molecular weight (kDa) of the marker proteins (Lane 1) are displayed on the left hand of the image. Bands were visualized using Coomassie stains.

| Recombinant Human NGAL Neutrophil Gelatinase-Associated Lipocalin (NGAL) is also known as lipocalin-2, 24 kDa alpha-2-microglobin-related subunit of MMP-9 and siderocalin. NGAL is a 198 amino acid 25 kDa secreted protein which possesses a lipid binding domain which enables it to bind small hydrophobic ligand molecules such as bacterial siderophores (Bauvois & Susin 2018, Abella et al. 2015). As well as the 25 kDa form, NGAL can exist as a 46 kDa homodimer and a 130 kDa heterodimer with MMP-9. The interaction with MMP-9 occurs in the extracellular space upon secretion of both proteins. It is through this interaction that MMP-9 proteolytic activity can be inhibited (Chakraborty et al. 2012). NGAL is expressed in various cell types including adipocytes, hepatocytes, pneumocytes, splenocytes, mesangial and microglial cells. NGAL has also been observed circulating at low levels in urine and blood of healthy subjects (40-109 ng/ml) . However it is overexpressed during various inflammatory, metabolic, neurologic and cancer pathologies. The higher levels of NGAL expression in these diseases have been correlated with disease severity and poor prognosis (Bauvois & Susin 2018, Chakraborty et al. 2012). This recombinant Human NGAL can be used to create a standard curve in a sandwich ELISA with purified Mouse anti Human NGAL antibody, clone D11-6D10 (MCA6198GA) as a capture antibody and biotinylated Mouse anti Human NGAL antibody, clone D02-7D4 (MCA6199B) as the detection antibody. |
