DESCRIPTION Synonym IL12,Interleukin-12,p70 Species Human A ccession P29459&P29460 Source HEK293 cells SPECIFICATIONS Amino acid sequence Arg23-Ser219&Ile23-Ser328 is expressed with a 10×His tag at the C terminus Molecular Weight 23.9kDa+36.1KD Purity >95.0% as determined by SDS-PAGE Endotoxin <5 EU·mg -1 Formulation Lyophilized from sterile PBS, pH 7.4.Normally 5%-8% trehalose and mannitol are added as protectants before lyophilization. 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 Active Recombinant Human IL-12 Protein was determined by SDS-PAGE with Coomassie Blue. 仅供科研用途，不可用于临床诊断！
