Used in neuroscience research to quantify levels of glial cell line-derived neurotrophic factor (GDNF) in biological samples from mice. Helps study neuroprotection, neuronal survival, and regeneration in models of neurodegenerative diseases such as Parkinson’s disease. Commonly applied in preclinical studies to evaluate the effectiveness of therapeutic interventions on GDNF expression. Also used in cell culture experiments to monitor GDNF secretion from glial cells and assess the impact of drugs or genetic modifications on neurotrophic support systems.
