Used in biomedical research to measure norepinephrine levels in rat samples, this ELISA kit enables accurate quantification of norepinephrine in plasma, serum, or tissue homogenates. It is widely applied in neuroscience and endocrinology studies to investigate stress responses, sympathetic nervous system activity, and neurotransmitter regulation. Researchers use it to evaluate changes in norepinephrine under experimental conditions such as drug treatment, behavioral studies, or disease models like hypertension, depression, and neurodegenerative disorders. The assay provides high sensitivity and specificity, allowing for reliable detection of small concentration changes, making it essential for preclinical studies involving rodent models.
