Used in biomedical research to detect and quantify receptor tyrosine kinase (RTK) activity in cell lysates or tissue samples. Enables researchers to study signal transduction pathways involved in cell growth, differentiation, and survival. Widely applied in cancer research to evaluate RTK phosphorylation states and assess the effectiveness of kinase inhibitors. Supports drug development and biomarker discovery by providing a reliable method for monitoring RTK expression and activation under various experimental conditions.
