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 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.
