Used in neuroscience and biomedical research to quantify dopamine-β-hydroxylase levels in biological samples such as serum, plasma, cerebrospinal fluid, and tissue homogenates. Enables researchers to study the enzyme's role in catecholamine metabolism, particularly the conversion of dopamine to norepinephrine. Applied in investigations of neurological and psychiatric disorders including Parkinson’s disease, Alzheimer’s disease, schizophrenia, and mood disorders. Also utilized in pharmacological studies assessing drug effects on the sympathetic nervous system and neuroendocrine function. The kit supports high-throughput screening and precise measurement, making it valuable for clinical research and biomarker validation.
