Used to measure glutamine synthetase (GS) enzyme activity in mouse tissue samples, particularly in research involving liver function, brain metabolism, and nitrogen metabolism. Widely applied in studies related to neurodegenerative diseases, hepatic encephalopathy, and metabolic disorders. Enables high-throughput analysis in preclinical studies and helps assess the impact of drugs or genetic modifications on GS activity. The kit provides a reliable and sensitive method for quantifying GS levels in cell lysates or tissue homogenates, supporting biomarker discovery and mechanistic investigations in mouse models.
