Used in immunological research to quantify levels of Toll-like receptor 3 (TLR3) in biological samples. Enables detection of TLR3 expression in response to viral infections, particularly double-stranded RNA viruses, due to TLR3's role in innate immunity. Commonly applied in studies involving antiviral responses, inflammation, and immune system activation. Supports research in vaccine development, autoimmune diseases, and cancer immunotherapy by providing a reliable method to measure TLR3 protein levels in cell lysates or tissue extracts. Widely used in academic, pharmaceutical, and clinical laboratories for mechanistic studies and biomarker validation.
