Used in neuroscience and pharmacological research to quantify dopamine receptor D5 levels in biological samples such as cell lysates or tissue homogenates. Helps investigate dopaminergic signaling pathways linked to cognitive function, attention, and disorders like ADHD, schizophrenia, and addiction. Enables researchers to assess changes in DRD5 expression under experimental conditions, evaluate drug effects on dopamine receptors, and support biomarker discovery in neurological and psychiatric diseases. Commonly applied in preclinical studies using mouse models to understand the role of D5 receptors in behavior and disease mechanisms.
