Product Summary
The Quantikine Canine IL-10 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure canine IL-10 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant canine IL-10 and antibodies raised against the recombinant protein. Results obtained for naturally occurring canine IL-10 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 natural canine IL-10.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times 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.

The recovery of canine IL-10 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Supernates (n=5) 93 75-104
EDTA Plasma (n=4) 89 83-93
Heparin Plasma (n=4) 87 83-93
Serum (n=5) 96 80-107
To assess the linearity of the assay, samples containing or spiked with high concentrations of canine IL-10 in each matrix were diluted with Calibrator Diluent RD6-12 and assayed.

Background: IL-10
Interleukin-10 functions as an anti-inflammatory cytokine by inhibiting the expansion and activation of Th1 cells and Th17 cells and by promoting the development of M2 macrophages and regulatory T cells (Treg). Within a tumor microrenvironment, however, IL-10 can inhibit the expansion of both Treg and myeloid-derived suppressor cells (MDSC). IL-10 exerts protective effects including limiting tissue damage in arthritic inflammation and promoting muscle regeneration after injury, but it also contributes to the persistence of viral infections. IL-10 signals through a receptor complex composed of IL-10 R alpha and IL-10 R beta. IL-10 R beta additionally associates with IL-20 R alpha, IL-22 R alpha 1, or IL-28 R alpha to form the receptor complexes for IL-22, IL-26, IL-28, and IL-29.

    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 4 times for a total of 5 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 5 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. Gently tap the plate to ensure thorough mixing. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
