Used in neuroscience research to quantify levels of neurotrophic factor 3 (NT-3) in biological samples such as serum, plasma, cerebrospinal fluid, and tissue homogenates. Helps investigate the role of NT-3 in neuronal survival, differentiation, and synaptic plasticity. Commonly applied in studies related to neurodegenerative diseases, nerve regeneration, and development of the nervous system. Enables researchers to assess changes in NT-3 expression under experimental conditions or in response to therapeutic interventions. Provides a sensitive and specific method for monitoring neurotrophic activity in rabbit models or cross-reactive species in preclinical studies.
