Background: Mouse Interleukin 33 (IL-33) is a 30 kDa proinflammatory cytokine which may also regulates gene transcription in producer cells. IL-33 is constitutively expressed in smooth muscle and airway epithelia. IL-33 was identified based on sequence and structural homology with IL-1 family cytokines. It is up-regulated in arterial smooth muscle, dermal fibroblasts, and keratinocytes following IL-1 alpha or IL-1 beta stimulation. IL-33 is structurally related to IL-1, which induces helper T cells to produce type 2 cytokines and acts through the receptor IL1RL-1. BindingIL-33 to this receptor activates NF-kappa-B and MAP kinases and induces in vitro Th2 cells to produce cytokines. In vivo, IL-33 induces the expression of IL-4, IL-5, IL-13 and also leads to severe pathological changes in mucosal organs.

Concentration:

Activity: Measure by its ability to induce proliferation in D10.G4.1 cells. The ED₅₀ for this effect is <40 pg/mL. The specific activity of recombinant mouse IL-33 is > 2 x 10⁷ IU/mg.

Sequence: Ser109-Ile266

Purity: > 98 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution: Please refer to the printed manual for detailed information.

Endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method.

Calculated MW: 18.5 kDa

ObservedMW: 17-25 kDa
