Product Summary
The Quantikine Mouse/Rat IL-22 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse and rat IL-22 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse IL-22 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse or rat IL-22 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse and rat IL-22.

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: IL-22
IL-22 (Interleukin-22) is a cytokine that induces the production of reactive oxygen species, IL-6, IL-10, and TNF-alpha as well as neutrophil infiltration during inflammation. It also supports the integrity of epithelial barriers and induces epithelial cell proliferation during wound healing. IL-22 signals through a receptor complex consisting of IL-22 R and IL-10 R beta. IL-10 R beta is a shared component of the receptor complexes for IL-10, IL-26, IL-28, and IL-29. IL-22 additionally binds to IL-22BP which blocks the interaction of IL-22 with IL-22 R.

    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. 100 µL Assay Diluent
    4.   Add 100 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 on a horizontal orbital microplate shaker.
    7.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

    8. 200 µL Conjugate
    9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
    10.   Aspirate and wash 5 times.

    11. 120 µL Substrate Solution
    12.   Add 120 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    13. 120 µL Stop Solution
    14.   Add 120 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
