Used to measure glucokinase (GCK) enzyme activity in mouse tissue samples, particularly in research related to glucose metabolism. Commonly applied in studies of diabetes, insulin regulation, and metabolic disorders. Enables quantification of GCK levels in pancreatic beta cells and liver tissues, helping assess enzyme function in response to drugs or genetic modifications. Supports high-throughput screening in preclinical research and aids in understanding the role of GCK in glucose homeostasis.
