Used in biomedical research to measure levels of glycogen synthase kinase 3β (GSK-3β) in rat tissue samples or cell lysates. This ELISA kit enables researchers to quantify active or total GSK-3β protein, supporting studies in signal transduction pathways, neurodegenerative diseases like Alzheimer's, diabetes, inflammation, and cancer. It is particularly valuable in preclinical studies involving rodent models where understanding the role of GSK-3β in disease progression or response to treatment is critical. The assay provides a sensitive and specific method for detecting changes in GSK-3β expression or phosphorylation state, aiding in the evaluation of potential therapeutic agents targeting this kinase.
