Product Summary for Canine IL-8/CXCL8 Quantikine ELISA Kit

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.

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.
