Used in biomedical research to quantify levels of glycogen synthase kinase 3β (GSK3β) in human samples such as cell lysates, tissue extracts, or biological fluids. This ELISA kit enables researchers to study GSK3β involvement in key signaling pathways including insulin signaling, Wnt pathway regulation, and neurodegenerative diseases like Alzheimer's. It is widely applied in studies related to diabetes, cancer, inflammation, and central nervous system disorders where GSK3β activity plays a regulatory role. The assay provides a sensitive and specific method to monitor changes in protein expression or phosphorylation state under experimental or pathological conditions.
