| Biochem/physiol Actions: | Human IL-33 is a proinflammatory protein that shares structural and functional characteristics with the IL-1 cytokine family. Recombinant human IL-33 is a 17.9 kDa protein containing 159 amino acid residues. |
| General description: | It binds and signals through the IL-1RL1/ST2 receptor activating NF-kappaB and MAP kinases. IL-33 induces production of TH2 cell related cytokines, including IL-4, IL-5 and IL-13, and exerts multiple inflammation related bioactivities. |
| Physical form: | Lyophilized from 10 mM Sodium Phosphate, pH 8.0 + 0.5 mM DTT. |
| Preparation Note: | Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C. |
