IL-33 Antibody (biotin)

IL-33 is a cytokine which belongs to the IL-1 superfamily, and it induces helper T cells to produce type 2 cytokines. This cytokine was previously named NF-HEV 'nuclear factor (NF) in high endothelial venules' (HEVs), as it was originally identified in these specialized cells. IL-33 mediates its biological effects by interacting with the receptors ST2 and IL-1 Receptor Accessory Protein, activating intracellular molecules in the NF-kappaB and MAP kinase signaling pathways that drive production of type 2 cytokines (e.g. IL-4, IL-5 and IL-13) from polarized Th2 cells. The induction of type 2 cytokines by IL-33 in vivo is believed to induce the the severe pathological changes observed in mucosal organs following administration of IL-33.

Produced from sera of rabbits pre-immunized with highly pure (>98%) recombinant hIL-33 (human IL-33) . Human IL-33 specific antibody was purified by affinity chromatography and then biotinylated.

IL-33 antibody is stable for at least 2 years from date of receipt at -20˚ C. The reconstituted antibody is stable for at least two weeks at 2-8˚ C. Frozen aliquots are stable for at least 6 months when stored at -20˚ C. Avoid repeated freeze-thaw cycles.
