Reconstitution Dissolved in sterile water, it is recommended to add 0.1% HSA or BSA for long-term preservation. STORAGE Stability and Storage 12 months from date of receipt at -20°C to -70°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for almost 6 months (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage. BACKGROUND Interleukin 9, also known as IL-9, is a cytokine (cell signaling molecule) belonging to the group of interleukins. IL-9 is a multifunctional cytokine secreted by TH2 lymphocytes. Interleukin-9 is reported to play important roles in innate and adaptive immunity in extrarenal inflammatory diseases. The tolerogenic cytokine IL9 promotes T regulatory cell function and allergic airway inflammation. Eliminating endogenous IL9 enabled sensitization of host T cells to tumors, leading to their early rejection without the requirement of vaccines or immunomodulatory therapies. IL-9 predominantly produced by TH17 cells synergizes with TGF-β1 to differentiate naive CD4+ T cells into TH17 cells, while IL-9 secretion by TH17 cells is regulated by IL-23. IL-9 has been demonstrated to be involved in several diseases, such as cancer, autoimmunity and other pathogen-mediated immune-regulated diseases. Data SDS-PAGE Bioactivity Recombinant Mouse IL-9 Protein was determined by SDS-PAGE with Coomassie Blue, showing a band at30-40 kDa. Measured in a cell proliferation assay using MC\/9 mouse mast cells. The ED50 for this effect is 1-5 ng\/mL.\u003c\/p\u003e","brand":"xfnano","offers":[{"title":"10 μg IL-9, Interleukin-9, IL9, Cytokine P40 106004 \/ Store at -20°C \/ 365days","offer_id":57280521699706,"sku":"106004","price":170.31,"currency_code":"USD","in_stock":true},{"title":"100 μg IL-9, Interleukin-9, IL9, Cytokine P40 106005 \/ Store at -20°C \/ 365days","offer_id":57280521732474,"sku":"106005","price":1139.06,"currency_code":"USD","in_stock":true},{"title":"500 μg IL-9, Interleukin-9, IL9, Cytokine P40 106006 \/ Store at -20°C \/ 365days","offer_id":57280521765242,"sku":"106006","price":3189.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0907\/3606\/6938\/files\/1_27871cef-ce01-415a-9a0e-d29d5e516d17.png?v=1780024497","url":"https:\/\/chinanano.com\/es\/products\/recombinant-mouse-il-9-protein-his-tag","provider":"xfnano","version":"1.0","type":"link"}
