Used for detecting and quantifying c-Jun N-terminal kinase (JNK) activity in duck samples, this ELISA kit is particularly valuable in veterinary research and avian disease studies. It enables researchers to monitor cellular stress responses, inflammation, and apoptosis pathways in ducks, which are crucial in understanding infections like avian influenza or other stress-related conditions. The kit supports high-throughput analysis in laboratories focused on poultry health, immunology, and molecular biology, providing a reliable tool for assessing JNK signaling in experimental models and disease diagnostics.
