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-7 (IL-7) was discovered in 1980s. It is one of the members of IL-2 superfamily. IL-7 is a cytokine that has been known since long in immunology, mainly regarding its effects on T-cells and B-cells. IL-7 has been demonstrated to be necessary for both B-cell and T-cell proliferation and lack of IL-7 causes immature immune cell arrest. IL7 and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. IL7 can be produced locally by intestinal epithelial and epithelial goblet cells and may serve as a regulatory factor for intestinal mucosal lymphocytes. IL-7 plays in aging may permit parsimonious preventative or therapeutic solutions for diverse conditions. Data SDS-PAGE Bioactivity Testing in progress Active Recombinant Mouse IL-7 Protein was determined by SDS-PAGE with Coomassie Blue.\u003c\/p\u003e","brand":"xfnano","offers":[{"title":"10 μg IL7,Interleukin-7 105998 \/ Store at -20°C \/ 365days","offer_id":57280521470330,"sku":"105998","price":146.88,"currency_code":"USD","in_stock":true},{"title":"100 μg IL7,Interleukin-7 105999 \/ Store at -20°C \/ 365days","offer_id":57280521503098,"sku":"105999","price":775.0,"currency_code":"USD","in_stock":true},{"title":"500 μg IL7,Interleukin-7 106000 \/ Store at -20°C \/ 365days","offer_id":57280521535866,"sku":"106000","price":2084.38,"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-7-protein-his-tag","provider":"xfnano","version":"1.0","type":"link"}
