Product Summary for Mouse/Rat IL-33 Quantikine ELISA Kit

The Quantikine Mouse/Rat IL-33 immunoassay is a 4.5 hour solid-phase ELISA designed to measure IL-33 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse mature IL-33 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate both recombinant mouse and rat IL-33. Results obtained using natural IL-33 showed dose response 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 IL-33.

Background: IL-33

IL-33 (Interleukin-33) is released from physically damaged or necrotic cells. It triggers Th2-biased immune cell activation at sites of inflammation as well as regulatory T cell and M2 macrophage expansion. It additionally induces angiogenesis, promotes tumor cell migration and invasion, limits cardiac myocyte hypertrophy, and limits the development of atherosclerotic plaques. IL-33 signals through a receptor complex composed of ST2 and IL-1 RAcP. IL-1 RAcP also associates with IL-1 RI, IL-1 RII, IL-1 R6, and SCF R/c-kit. Soluble isoforms of ST2 and IL-1 RAcP function as decoy receptors that regulate IL-33 bioactivity.
