Used in neuroscience and immunology research to quantify glutamate decarboxylase (GAD) levels in mouse samples. Helps study GAD's role in GABA synthesis and its involvement in neurological disorders such as epilepsy, Parkinson’s disease, and autism. Also applied in diabetes research since GAD is a major autoantigen in type 1 diabetes. Enables high-throughput screening of immune responses and neuronal function in experimental models.
