Anti-hIL-18

Neutralizing IgG monoclonal antibody to human interleukin 18

Anti-hIL-18-IgG is a monoclonal antibody specific for human interleukin 18 (hIL-18). It has been selected for its ability to efficiently neutralize the biological activity of hIL-18. Anti-hIL-18-IgG was generated by recombinant DNA technology.

Interleukin 18 (IL-18; formerly called interferon-γ inducing factor) is a pro-inflammatory cytokine that causes a wide variety of biological effects associated with infection, inflammation and autoimmune processes [1, 2].

More specifically, IL-18 induces IFN-γ production and contributes to T-helper 1 (Th1) cell polarization. IL-18 is produced by macrophages and other cells, as a proprotein which is proteolytically processed to its active form by caspase 1, an enzyme that is activated within the inflammasome multiprotein complex. IL-18 binds to a heterodimeric receptor consisting of IL-18R and IL-18 receptor accessory protein (IL-18RAP). Upon binding, IL-18 activates NF-κB and AP-1 via signaling pathways that involve IRAK and TRAF-6 [3, 4].

Anti-hIL-18-IgG has been produced in Chinese hamster ovarian (CHO) cells and purified by affinity chromatography.
