Used in immunological research to quantify mouse Toll-like receptor 3 (TLR3) levels in biological samples such as serum, plasma, cell lysates, and tissue homogenates. Enables researchers to study TLR3 expression in response to viral infections, as TLR3 plays a key role in recognizing double-stranded RNA and activating innate immune responses. Commonly applied in studies involving inflammation, antiviral immunity, and autoimmune diseases in mouse models. Supports high-throughput screening and mechanistic studies in drug development and vaccine research.
