Used in biomedical research to quantify oxytocin levels in rat biological samples such as plasma, serum, or tissue homogenates. Enables researchers to study the role of oxytocin in social behaviors, stress responses, reproductive functions, and maternal bonding in rodent models. Commonly applied in neuroscience, endocrinology, and behavioral studies to investigate hormonal changes under experimental conditions. Provides a sensitive and specific measurement, supporting high-throughput analysis in preclinical studies.
