Used to measure dopamine-β hydroxylase levels in biological samples such as serum, plasma, or tissue homogenates. This assay is commonly applied in neuroscience and psychiatric research to study the sympathetic nervous system and catecholamine metabolism. It helps investigate conditions like heart failure, hypertension, neurodegenerative diseases, and mental health disorders including schizophrenia and PTSD. The kit enables quantitative detection, supporting both clinical research and drug development studies focused on noradrenergic pathways.
