Used in veterinary research and immunology studies to detect and quantify secretory IgA in canine samples, this ELISA kit helps assess mucosal immune responses in dogs. It is commonly applied in monitoring gastrointestinal health, evaluating vaccine efficacy, and studying immune function in conditions like inflammatory bowel disease or food allergies. Researchers also use it to investigate the impact of probiotics, diet, and environmental stressors on the canine immune system. The kit supports high-throughput analysis and provides a reliable tool for measuring immune activity at mucosal surfaces such as the gut and respiratory tract.
