Used to measure dopamine beta-hydroxylase (DBH) enzyme activity in human biological samples such as serum, plasma, or tissue extracts. This ELISA kit is commonly applied in neuroscience and clinical research to study disorders related to catecholamine metabolism, including neurodegenerative diseases like Parkinson’s, psychiatric conditions such as schizophrenia and depression, and cardiovascular diseases. It enables researchers to quantify DBH levels accurately, helping assess sympathetic nervous system function and the balance between dopamine and norepinephrine. The assay supports high-throughput analysis and is valuable in biomarker studies and drug development where DBH modulation is a target.
