Used in biomedical research to measure levels of cholecystokinin (CCK), a hormone involved in digestion and appetite regulation. The kit enables researchers to quantify CCK in tissue samples or biological fluids, supporting studies on gastrointestinal function, pancreatic secretion, gallbladder contraction, and satiety signaling. Commonly applied in preclinical studies, metabolic research, and neuroscience to understand CCK’s role in feeding behavior, anxiety, and pain modulation. Provides a sensitive and specific method for high-throughput analysis in laboratory settings.
