Human NGAL (Lipocalin-2) ELISA Kit | LCN2 elisa kit
Human NGAL ELISA Kit
Principle of the Assay: This assay is a sandwich Enzyme Linked-Immunosorbent Assay (ELISA) for the measurement of mouse Lipocalin-2 in cell culture supernatants, serum and plasma. A polyclonal antibody specific for Lipocalin-2 has been pre-coated onto the 96-well microtiter plate. Standards (STD) and samples are pipetted into the wells for binding to the coated antibody. After extensive washing to remove unbound compounds, Lipocalin-2 is recognized by the addition of a biotinylated polyclonal antibody specific for mouse Lipocalin-2 (DET). After removal of excess biotinylated antibody, streptavidin-peroxidase (STREP-HRP) is added. Following a final washing, peroxidase activity is quantified using the substrate 3,3',5,5'-tetramethylbenzidine (TMB). The intensity of the color reaction is measured at 450 nm after acidification and is directly proportional to the concentration of mouse Lipocalin-2 in the samples!!Background/Introduction: Lipocalin-2 (LCN2), also known as neutrophil gelatinase-associated lipocalin (NGAL), 24p3, or neutrophil lipocalin (NL), is a 25-kDa secretory glycoprotein (1). Lipocalin 2 was initially defined as a powerful bacteriostatic agent active against various Gramnegative microorganisms through impeding bacterial iron sequestration (2, 3). LCN2 also functions as a stress protein that is released in a variety of other sterile inflammatory conditions such as adipose obesity-related inflammation and cancer (2, 3). LCN2 is over-expressed in many types of cancers including breast, pancreatic, and ovarian carcinomas and promotes tumorigenesis through enhancing tumor cell survival and proliferation, and metastatic potential (4, 5, 6). Furthermore, a growing body of evidence suggests that serum levels of lipocalin-2 are correlated with obesity, insulin resistance, hyperglycemia, coronary heart disease, acute renal injury and fatty liver disease (7, 8, 9).
NCBI and Uniprot Product Information
Uniprot Description
LCN2: Iron-trafficking protein involved in multiple processes such as apoptosis, innate immunity and renal development. Binds iron through association with 2,5-dihydroxybenzoic acid (2,5- DHBA), a siderophore that shares structural similarities with bacterial enterobactin, and delivers or removes iron from the cell, depending on the context. Iron-bound form (holo-24p3) is internalized following binding to the SLC22A17 (24p3R) receptor, leading to release of iron and subsequent increase of intracellular iron concentration. In contrast, association of the iron-free form (apo-24p3) with the SLC22A17 (24p3R) receptor is followed by association with an intracellular siderophore, iron chelation and iron transfer to the extracellular medium, thereby reducing intracellular iron concentration. Involved in apoptosis due to interleukin-3 (IL3) deprivation: iron-loaded form increases intracellular iron concentration without promoting apoptosis, while iron-free form decreases intracellular iron levels, inducing expression of the proapoptotic protein BCL2L11/BIM, resulting in apoptosis. Involved in innate immunity, possibly by sequestrating iron, leading to limit bacterial growth. Belongs to the calycin superfamily. Lipocalin family. 2 isoforms of the human protein are produced by alternative splicing.
