Used in neuroscience research to quantify levels of neurotrophic factor 3 (NT-3) in biological samples such as brain tissue, cerebrospinal fluid, or cell culture supernatants. Helps investigate the role of NT-3 in neuronal survival, differentiation, and synaptic plasticity. Commonly applied in studies related to neurodegenerative diseases, nerve injury, and neuroregeneration. Enables researchers to assess changes in NT-3 expression under experimental conditions, supporting drug development and mechanistic studies in rodent models.
