Used in biomedical research to quantify levels of human α-spectrin (SPTAN1) in cell lysates, tissue extracts, and biological fluids. This ELISA kit enables detection of SPTAN1, a structural protein involved in maintaining cytoskeletal integrity, particularly in neurons. It is widely applied in neuroscience studies to assess neuronal damage, as SPTAN1 breakdown products are markers of apoptosis and neurodegeneration. Researchers use this kit in models of traumatic brain injury, stroke, and neurodegenerative diseases such as Alzheimer's and Parkinson's to monitor cellular injury and evaluate therapeutic interventions. The assay provides a sensitive and specific means to measure SPTAN1 concentration, supporting both basic research and drug development.
