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-12 (IL-12), is a cytokine that is secreted by activated phagocytes and dendritic cells and that induces interferon-γproduction by natural-killer and T lymphocytes. IL-12 (referred to as 'p70') is a 70 kDa heterodimer composed of a 35 kDa subunit (IL-12A p35) and a 40 kDa subunit (IL-12B p40). IL12 act as a growth factor for activated T and NK cells, enhance the lytic activity of NK\/lymphokine-activated Killer cells, and stimulate the production of IFN-gamma by resting PBMC. IL-12 also has anti-angiogenic activity, which means it can block the formation of new blood vessels. IL-12 has been shown to play a critical role in the pathogenesis of a variety of immune-related diseases. Data SDS-PAGE Bioactivity Testing in progress Active Recombinant Rat IL-12 Protein was determined by SDS-PAGE with Coomassie Blue.\u003c\/p\u003e","brand":"xfnano","offers":[{"title":"10 μg IL12,Interleukin-12,p70 106053 \/ Store at -20°C \/ 365days","offer_id":57280523207034,"sku":"106053","price":179.69,"currency_code":"USD","in_stock":true},{"title":"100 μg IL12,Interleukin-12,p70 106054 \/ Store at -20°C \/ 365days","offer_id":57280523239802,"sku":"106054","price":745.31,"currency_code":"USD","in_stock":true},{"title":"500 μg IL12,Interleukin-12,p70 106055 \/ Store at -20°C \/ 365days","offer_id":57280523272570,"sku":"106055","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\/fr\/products\/recombinant-rat-il-12-protein-his-tag","provider":"xfnano","version":"1.0","type":"link"}
