Used in immunological research to quantify porcine interleukin-18 levels in biological samples such as serum, plasma, and cell culture supernatants. Enables study of inflammatory responses in pig models, supporting research in veterinary medicine, infectious disease, and vaccine development. Helps assess immune activation in studies related to viral infections, sepsis, and autoimmune conditions in swine. Suitable for preclinical evaluation of therapeutics targeting the IL-18 pathway.
