Used to measure glucose-6-phosphatase (G-6-Pase) enzyme activity in human biological samples such as serum, plasma, or cell lysates. This assay is commonly applied in research settings to study glucose metabolism, particularly in conditions like diabetes, metabolic disorders, and liver diseases where G-6-Pase plays a key role in gluconeogenesis and glycogenolysis. The kit enables quantitative analysis, helping researchers assess enzyme function and evaluate the impact of drugs or genetic modifications on metabolic pathways. It is also useful in clinical investigations exploring insulin resistance and metabolic syndrome.
