Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg\/mL. Stock solutions should be apportioned into working aliquots and stored at \u0026lt;-20°C. Further dilutions should be made in appropriate buffered solutions.\u003c\/p\u003e\n\n\u003cp\u003eStorage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze\/thaw cycles.\u003c\/p\u003e\n\n\u003cp\u003eUsage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.

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.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"2µg","offer_id":42882222031027,"sku":"PR2024-2","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"10µg","offer_id":42882222063795,"sku":"PR2024-10","price":490.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_aaafa67b-d89c-46ab-9c74-81e234b403c8.jpg?v=1702049535","url":"https:\/\/afsbio.com\/products\/recombinant-murine-interleukin-33-rmuil-33-pr2024","provider":"AFSBio Inc.","version":"1.0","type":"link"}
