Product Description

Human NGAL (Neutrophil gelatinase-associated lipocalin) is encoded by the LCN2 gene. NGAL is involved in innate immunity by sequestrating iron that in turn limits bacterial growth. It is expressed in neutrophils and in low levels in the kidney, prostate, and epithelia of the respiratory and alimentary tracts. NGAL is used as a biomarker of kidney injury1,2, and other cardiovascular disease and cancer3,4. NGAL can be measured in different samples, such as plasma, serum, urine3, or tissue homogenates, using ELISA (enzyme-linked immunosorbent assay) kits.
