Used in neuroscience and biomedical research to quantify levels of actinin α protein specifically expressed in the human striatum. This ELISA kit enables researchers to study changes in actinin α expression associated with neurodegenerative diseases such as Huntington's disease and Parkinson's disease. It is also applied in investigating synaptic stability and neuronal cytoskeletal dynamics. The kit supports analysis of brain tissue samples, cerebrospinal fluid, and neuronal cell cultures, providing a tool for biomarker discovery and evaluation of therapeutic interventions targeting striatal function.
