Product Summary
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.

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.

Background: Lipocalin-2/NGAL
The Lipocalin family comprises a diverse group of mostly secreted soluble proteins that bind hydrophobic ligands and act as transporters, carrying small molecules to specific cells. Lipocalins are related by possessing an 8-stranded beta-barrel structure. Lipocalin-1, also named tear lipocalin (TL), von Ebners gland protein (VEG) and tear pre-albumin, binds a large number of hydrophobic molecules and exhibits cysteine proteinase inhibitor and endonuclear activities. Lipocalin-2, also known as neutrophil gelatinase-associated lipocalin (NGAL), is a component of granules in neutrophils from tissues that are normally exposed to microorganisms and is upregulated during inflammation. Lipocalin-2 can form homodimers and can heterodimerize with the neutrophil gelatinase MMP-9.

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 50 µL Assay Diluent
    4.   Add 50 µL of Assay Diluent to each well.

    5. 50 µL Standard, Control, or Sample
    6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
    7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    8. 100 µL Conjugate
    9.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
    10.   Aspirate and wash 4 times.

    11. 100 µL Substrate Solution
    12.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.

    13. 100 µL Stop Solution
    14.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
