IL-18BP protein regulates immune processes by binding to interleukin-18 (IL-18), inhibiting its activity. This interaction positions IL-18BP as a key inhibitor of the early TH1 cytokine response, emphasizing its role in immune modulation and potential contribution to regulating inflammatory responses. IL-18BP Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived IL-18BP protein, expressed by HEK293 , with C-hFc labeled tag.
