Used to measure glutamic acid decarboxylase (GAD) enzyme activity in mouse samples, particularly in research related to autoimmune diseases such as type 1 diabetes and neurological disorders. The kit enables quantification of GAD activity in pancreatic tissues or serum, helping in the study of autoantibody development and immune responses. It is also applied in neuroscience research to investigate GABAergic neuron function and the role of GAD in neurotransmission. The assay supports high-throughput screening and provides a reliable tool for monitoring disease progression and evaluating therapeutic interventions in mouse models.
