{"product_id":"cst-79627s","title":"CST,  79627S, Human IL-13 Recombinant Protein","description":"Growth Factors and Cytokines for studying IL13 in the research area.\n\n\u003cb\u003eStorage\u003c\/b\u003e\nHuman IL-13 Recombinant Protein is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile 20 mM HCl at a concentration of 0.1 mg\/mL which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Once in solution, store at 4°C and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze\/thaw cycles if storing reconstituted material at -20ºC to -80ºC.\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nRecombinant human IL-13 was expressed in and is supplied in a lyophilized form.\n\u003cb\u003eBackground\u003c\/b\u003e\nInterleukin-13 (IL-13) is produced by T cells and is important in the TH2 response. IL-13 targets include B cells, eosinophils, fibroblasts, mast cells, and macrophages (1-3). IL-13 binds specifically to IL-13Rα1 that complexes with IL-4Rα to form the Type II IL-4R. Jak1 and Tyk2 are activated and signal through Stat3 and Stat6 (6). IL-13Rα2 is a different gene product, lacks the intracellular domain, does not complex with IL-4Rα, and does not signal (1,6,7). The extracellular domain of IL-13Rα2 is often elevated in diseased states. IL-13 plays key roles in airway hyperresponsiveness (AHR) of allergic asthma (1,4,5) and modulates resistance to parasitic organisms (1).","brand":"CST","offers":[{"title":"Default Title","offer_id":46800716791977,"sku":"79627S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-79627s","provider":"Iright","version":"1.0","type":"link"}
