Used in biomedical research to quantify FoxO1 protein levels in cell lysates, tissue extracts, and biological fluids. Enables investigation of insulin signaling, glucose metabolism, and cellular responses to oxidative stress. Widely applied in studies related to diabetes, aging, cancer, and metabolic disorders. Supports high-throughput screening in drug development and evaluation of therapeutic targets involving the PI3K/Akt/FoxO signaling pathway. Provides a reliable, sensitive, and specific method for monitoring FoxO1 activation and expression changes in experimental models.
