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 23 (IL-23) is a member of the IL-12 cytokine family and composed of two subunits, IL-12p40 and IL-23p19. heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 binds to an heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. The main biological effects of IL-23 identified initially consist of stimulation of antigen presentation by DCs, T cell differentiation to Th17 cells, and production of interferon-γ (IFN-γ). IL-23 acts also as an end-stage effector cytokine through direct action on macrophages. Data SDS-PAGE Bioactivity Active Recombinant Human IL-23 Protein was determined by SDS-PAGE with Coomassie Blue. 仅供科研用途，不可用于临床诊断！
