Product Summary for Mouse Lipocalin-2/NGAL Quantikine ELISA Kit
The Quantikine Mouse Lipocalin-2/NGAL Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse Lipocalin-2 in cell culture supernates, mouse serum, platelet-poor plasma, and urine. It contains NS0-expressed recombinant mouse Lipocalin-2 and antibodies raised against the recombinant factor. Natural mouse Lipocalin-2 showed dose-response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards, indicating that this kit can be used to determine relative levels of natural mouse Lipocalin-2.

Sample Values
Serum/Platelet-poor Plasma/Urine - Samples were evaluated for the presence of mouse
Lipocalin-2 in this assay.
Cell Culture Supernates:
Two mouse brains and kidneys were homogenized and seeded in RPMI 1640 supplemented with 10% fetal bovine serum, 5 μM beta-mercaptoethanol, 2 mM L-glutamine, 100 U/mL of penicillin, and 100 μg/mL of streptomycin sulfate. The resulting supernates were either untreated or stimulated with 1 μg/mL of LPS for 3 days. Aliquots of the cell culture supernates were removed and assayed for levels of mouse Lipocalin-2.
| Sample Type | Mean (ng/mL) | Range (ng/mL) | Standard Deviation (ng/mL) |
| Serum (n=20) | 141 | 58.3-290 | 60.2 |
| Platelet-poor heparin plasma (n=20) | 76.0 | 40.7-143 | 30.1 |
| Platelet-poor EDTA plasma (n=20) | 54.1 | 32.5-74.7 | 12.3 |
| Urine (n=20) | 48.6 | 12.9-168 | 34.1 |
Cell Culture Supernates:
J774A.1 mouse reticulum cell sarcoma macrophage cells (1 x 106
cells/mL) were cultured in
RPMI supplemented with 10% fetal bovine serum, 2 mM L-glutamine, 100 U/mL of penicillin,
and 100 μg/mL of streptomycin sulfate. Cells were either untreated or stimulated with
100 ng/mL of recombinant mouse IFN-gamma and 1 μg/mL of lipopolysaccharide (LPS) for 2 days.
Aliquots of the cell culture supernates were removed and assayed for levels of mouse
Lipocalin-2.
| Condition | Observed Values (ng/mL) |
| Unstimulated | 0.817 |
| Stimulated | 161 |
WEHI-3 myelomonocytic leukemia cells (2 x 105
cells/mL) were cultured in RPMI supplemented
with 10% fetal bovine serum, 2 mM L-glutamine, 100 U/mL of penicillin, and 100 μg/mL of
streptomycin sulfate. Cells were either untreated or stimulated with 1 μg/mL of LPS for 4 days.
Aliquots of the cell culture supernates were removed and assayed for levels of mouse
Lipocalin-2.
| Condition | Observed Values (ng/mL) |
| Unstimulated | 83.7 |
| Stimulated | 178 |

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Recovery for Mouse Lipocalin-2/NGAL Quantikine ELISA Kit
The recovery of mouse Lipocalin-2 spiked to three levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Samples (n=4) | 93 | 82-101 |
Linearity
To assess the linearity of the assay, samples containing high concentrations of mouse Lipocalin-2 were diluted with Calibrator Diluent and then assayed.
