Polyacrylamide Gel Electrophoresis (PAGE) is a powerful technique used to separate proteins based on molecular weight, particularly through SDS-PAGE. In this virtual lab setup, students learn proper sample preparation, gel casting, and result visualization. SDS ensures proteins carry uniform negative charges, enabling size-based separation within stacking and separating gels. Applications include protein sizing, purification, immunoblotting, and clinical diagnostics such as serum protein analysis for disease detection.
