Used primarily in protein electrophoresis, this gel facilitates the separation of proteins based on their molecular weight. It is particularly effective for resolving proteins in the range of 10 to 200 kDa, making it suitable for various applications in biochemistry and molecular biology. Researchers commonly use it for SDS-PAGE to analyze protein purity, quantify protein expression, and assess molecular weight standards. The precast format ensures consistency and saves preparation time, while the glass plate construction provides durability and clarity for imaging. It is widely employed in laboratories for routine protein analysis, Western blotting, and other protein characterization studies.
