Used in biomedical research to quantitatively measure Interferon Regulatory Factor 7 (IRF7) levels in cell lysates, tissue extracts, or biological fluids such as serum and plasma. This kit is essential for studying the regulation of type I interferon responses, particularly in immune system research, viral infection studies, and inflammation-related diseases. Researchers use it to evaluate IRF7 activation in signaling pathways linked to antiviral defense, autoimmunity, and cancer immunology. The assay supports high-throughput screening and mechanistic studies in both basic science and drug development settings.
