Product Summary

The Quantikine Canine IL-8 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure canine IL-8 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant canine IL-8 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural canine IL-8 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 canine IL-8.

Precision

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

Background: IL-8/CXCL8

Interleukin-8 (IL-8), also known as CXCL8, is a chemokine that is upregulated at sites of inflammation where it promotes neutrophil infiltration and activation. IL-8 can form homodimers and heterodimers with CXCL4/PF4. Its bioactivity is regulated by proteolytic truncations, citrullination, and the decoy receptor DARC. IL-8 signals through CXCR1/IL-8 RA, which is also used by CXCL6, and through CXCR2/IL-8 RB, which is used by multiple CXC chemokines. IL-8 also binds to Serpin A1/alpha-1 Antitrypsin which prevents IL-8 interaction with CXCR1.

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. Tap the plate gently for 1 minute. 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.
