Under homeostatic conditions, the full-length protein (270 amino acids in the canonical human sequence) is constitutively expressed in the nucleus of barrier epithelial cells and endothelial cells, where it acts as a chromatin-associated transcriptional repressor. Upon cellular damage or necrosis, IL-33 is released into the extracellular space and functions as an \"alarmin\" that signals through the ST2 (IL1RL1) receptor complex, activating NF-κB and MAPK pathways to drive type 2 immune responses. Its biological activities include promoting Th2 cell maturation, activating mast cells, basophils, eosinophils, and NK cells, and inducing the production of IL-4, IL-5, and IL-13. The mature, biologically active form of human IL-33 is generated by proteolytic cleavage (e.g., by caspase-1) and is commonly produced recombinantly in E. coli as a non-glycosylated polypeptide of approximately 159–160 amino acids with a molecular weight of about 17.9–18.1 kDa. Given its central role in allergic inflammation, tissue repair, and tumor immunity, IL-33 is an important research target and a potential therapeutic candidate.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"1x96T","offer_id":67455364497483,"sku":"S0C3259-1x96T","price":500.0,"currency_code":"USD","in_stock":true},{"title":"5x96T","offer_id":67455364530251,"sku":"S0C3259-5x96T","price":2420.0,"currency_code":"USD","in_stock":true},{"title":"10x96T","offer_id":67455364563019,"sku":"S0C3259-10x96T","price":4670.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/aeafabd13de44fed9e3b08b8d80a3948_23e7cba3-4db6-4589-96ac-673e6112f7ef.jpg?v=1794510016","url":"https:\/\/www.antbioinc.com\/products\/human-il-33-culture-media-onestep-elisa-kit-s0c3259","provider":"AntBio","version":"1.0","type":"link"}
