Used in biomedical research to measure levels of glycogen synthase enzyme in rat tissue samples, particularly in studies related to glucose metabolism and insulin signaling. Commonly applied in diabetes and metabolic syndrome research to evaluate enzyme activity changes in liver or muscle tissues. Enables researchers to assess the impact of drugs, diet, or genetic modifications on glycogen storage and metabolic pathways in rat models. Provides a reliable, high-throughput method for quantifying GS protein concentration in experimental settings.
