Product overview
Mouse Lipocalin-2 ELISA Kit (NGAL) (ab199083) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Lipocalin-2 (NGAL) protein in cit plasma, serum, urine, edta plasma, and cell culture supernatant. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse Lipocalin-2 (NGAL) with 1.1 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
Lipocalin-2 (also known as Neutrophil gelatinase-associated lipocalin or NGAL) is an iron binding and iron trafficking protein. Lipocalin-2 is involved in multiple cellular processes including apoptosis, innate immunity and renal development. Mice deficient in Lipocalin-2 appear normal but have increased susceptibility to bacterial infection. The bacteriostatic function may be related to Lipocalin-2 limiting bacterial iron supply. Mouse Lipocalin-2 has 81% and 62% protein sequence identity to rat and human Lipocalin-2, respectively.

Function
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. -
Tissue specificity
Expressed in bone marrow and in tissues that are prone to exposure to microorganism. High expression is found in bone marrow as well as in uterus, prostate, salivary gland, stomach, appendix, colon, trachea and lung. Not found in the small intestine or peripheral blood leukocytes. -
Sequence similarities
Belongs to the calycin superfamily. Lipocalin family. -
Cellular localization
Secreted. Upon binding to the SLC22A17 (24p3R) receptor, it is internalized. - Information by UniProt

Standard curve comparison between mouse Lipocalin-2 (NGAL) SimpleStep ELISA® kit and traditional ELISA kit from leading competitor. SimpleStep ELISA kit shows a 7-fold increase in sensitivity.
-
Background-subtracted data values (mean +/- SD) are graphed.
-
The concentrations of Lipocalin-2 were measured in duplicate and interpolated from the Lipocalin-2 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Lipocalin-2 concentration was determined to be 265.2 ng/mL in mouse serum, 583.8 ng/mL in mouse plasma (Citrate), and 535.2 ng/mL in platelet poor mouse plasma (EDTA).

J774A.1 cells were grown in the absence (unstimulated) or presence of Phorbol Myristate Acetate (PMA) and phytohemagglutinin (PHA) (stimulated) for 3 days. Raw data from duplicate measurements are plotted (mean +/- SD, n=2).
-
L929 and J774A.1 cells were grown in the absence (unstimulated) or presence of Phorbol Myristate Acetate (PMA) and phytohemagglutinin (PHA) (stimulated) for 3 days. RAW264.7 were grown in the absence (unstimulated) or presence of LPS (stimulated) for 2 days. Cell Culture supernatant was diluted to within the range of the assay, 5-fold (L929 and J774A.1) or 2,000-fold (RAW264.7). Measured values were interpolated from the Lipocalin-2 Standard Curve diluted in Sample Diluent NS and corrected for dilution factor. Mean of duplicate values +/-SD are graphed. Lipocalin-2 was undetectable in media.
