Used in biomedical research to measure levels of oxyntomodulin (OXM) in biological samples such as serum or plasma. Helps investigate gut-brain signaling, appetite regulation, and metabolic disorders like obesity and type 2 diabetes. Commonly applied in preclinical studies to evaluate hormonal responses to food intake, drug treatments, or genetic modifications affecting gastrointestinal function. Provides a reliable, high-throughput method for quantifying OXM in rodent models, supporting studies on energy balance and gastrointestinal physiology.
