Canine IL-10 Quantikine ELISA Kit Summary

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.

Preparation and Storage

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 datasheet for the 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.     Add 50 μL of Assay Diluent to each well.

4.     Add 50 μL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.

5.     Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

6.     Add 100 μL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.

7.     Aspirate and wash 5 times.

8.     Add 100 μL Substrate Solution to each well.

9.     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.
