Used in neuroscience and biomedical research to quantitatively measure dopamine decarboxylase (DDC) enzyme levels in human biological samples such as serum, plasma, cerebrospinal fluid, and tissue homogenates. This ELISA kit is particularly valuable in studies related to dopamine metabolism, neurodegenerative disorders like Parkinson’s disease, and psychiatric conditions such as depression and schizophrenia. It enables researchers to assess DDC activity indirectly by measuring protein concentration, supporting investigations into neurotransmitter regulation and potential therapeutic targets. The assay is widely used in clinical labs and pharmaceutical research for its sensitivity, specificity, and reliability in detecting small changes in DDC expression.
