Used in immunological research to quantify Duck Toll-like Receptor 4 (TLR4) levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study the activation of innate immune responses in ducks, particularly in response to pathogens like bacteria and viruses. It is widely applied in veterinary research, vaccine development, and disease surveillance to assess immune system function and monitor inflammatory responses. The assay supports high-throughput analysis with reliable sensitivity and specificity, making it valuable for studies in avian immunology and infectious disease dynamics.
