Used in immunological research to detect and quantify RIG-I-like receptor proteins, which play a key role in innate immune responses against viral infections. The kit enables researchers to measure RLR levels in biological samples such as cell lysates or tissue homogenates, supporting studies on antiviral signaling pathways, immune activation, and inflammatory diseases. It is widely applied in virology, vaccine development, and drug discovery to assess the modulation of RLR expression under experimental conditions.
