Its protein structure consists of four α-helices (A, B, C, D) stabilized by two disulfide bonds forming a compact globular conformation, and recombinant expression with His-tag technology facilitates purification and structural studies. This cytokine activates the JAK1\/TYK2-STAT6 signaling pathway through type I receptors (IL-13Rα1\/IL-4Rα heterodimer), regulating B cell IgE class switching, mucus production, and eosinophil chemotaxis; concurrently, binding to IL-13Rα2 (decoy receptor) participates in inflammatory modulation and tissue fibrosis. In clinical medicine, IL-13 serves as a core driver of type 2 inflammatory diseases, with biologics targeting the IL-4\/IL-13 pathway such as dupilumab approved for treating moderate-to-severe asthma, atopic dermatitis, and chronic rhinosinusitis with nasal polyps. Furthermore, IL-13 receptor α2 is highly expressed in solid tumors including glioblastoma, emerging as a novel tumor target for CAR-T cells and bispecific antibodies, demonstrating broad clinical application prospects spanning from inflammatory regulation to cancer immunotherapy.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"UA BIOSCIENCE","offers":[{"title":"25μg","offer_id":42332772794443,"sku":null,"price":330.0,"currency_code":"USD","in_stock":true},{"title":"100μg","offer_id":42332772827211,"sku":null,"price":700.0,"currency_code":"USD","in_stock":true},{"title":"500μg","offer_id":42332772859979,"sku":null,"price":1400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/AntBioImage_c1a368db-cdc6-4117-9b91-781e6d44b08f.png?v=1776073866","url":"https:\/\/www.antbioinc.com\/products\/il-13-his-tag-protein-human-ua016041","provider":"AntBio","version":"1.0","type":"link"}
