Used to quantitatively measure interleukin-18 (IL-18) levels in human biological samples such as serum, plasma, or cell culture supernatants. IL-18 is a pro-inflammatory cytokine involved in immune regulation, making this kit valuable in research on inflammatory diseases, autoimmune disorders, and cancer. It supports studies in immunology, infectious diseases, and therapeutic development by providing accurate and sensitive detection of IL-18 concentrations.
