Used for measuring glycogen synthase kinase (GSK) activity in rat samples, this ELISA kit is widely applied in research related to cellular signaling pathways, particularly the Wnt and insulin signaling pathways. It enables researchers to quantify phosphorylation levels of GSK substrates, helping assess kinase function in metabolic regulation, neurodegenerative diseases, and cancer development. The kit is commonly used in preclinical studies involving rat models to evaluate the impact of drugs or genetic modifications on GSK-mediated processes such as glucose metabolism, cell proliferation, and apoptosis. Its high sensitivity and specificity make it suitable for monitoring changes in GSK activity in tissue extracts, cell lysates, and biological fluids.
