Tested Applications

• Positive WB detected in: PMA, LPS and Brefeldin A treated THP-1 cells, Recombinant protein
• Positive IHC detected in: human tonsillitis tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:500-1:2000
• Immunohistochemistry (IHC): IHC : 1:200-1:800

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

IL-33 is an IL-1 family cytokine and nuclear alarmin, is constitutively expressed in epithelial barrier tissues and human blood vessels. IL-33 is involved in the maturation of Th2 cells and the activation of mast cells, basophils, eosinophils and natural killer cells. It also acts as a chemoattractant for Th2 cells, and may function as an "alarmin", that amplifies immune responses during tissue injury.
