Used in biomedical research to quantify mTOR protein levels in cell or tissue samples. Enables study of mTOR signaling pathway activity, which plays a key role in cell growth, proliferation, and survival. Widely applied in cancer research, metabolic disease studies, and aging-related investigations. Supports evaluation of drug effects, especially for rapamycin and other mTOR inhibitors, by measuring changes in protein expression or activation states. Provides a reliable, high-throughput method for screening therapeutic compounds and understanding cellular responses under various experimental conditions.
