Used to quantitatively measure interferon-beta (IFN-β) levels in biological samples such as serum, plasma, cell culture supernatants, and tissue lysates from mice. This assay is widely applied in immunology and inflammation research to study the innate immune response, particularly in models of viral infection, autoimmunity, and cancer. It helps researchers evaluate the activation of type I interferon pathways, assess the efficacy of therapeutic agents that modulate immune responses, and investigate diseases like multiple sclerosis using mouse models. The kit provides high sensitivity and specificity, enabling accurate detection of low concentrations of IFN-β, which is critical for understanding immune regulation and developing new treatments.
