Used in biomedical research to measure levels of glycogen synthase kinase (GSK) in rat samples, this ELISA kit enables accurate quantification of GSK activity in tissue extracts or cell lysates. It is widely applied in studies related to insulin signaling, glucose metabolism, and diabetes research. The kit supports investigation of pathways involved in metabolic disorders, neurodegenerative diseases, and inflammation, where GSK plays a regulatory role. Its high sensitivity and specificity make it suitable for monitoring changes in GSK expression under experimental treatments, aiding in drug development and mechanistic studies in preclinical models.
