Tris-Glycine precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 4-15% gradient allows for the resolution of a broad range of protein sizes, making it versatile for various applications. These gels are particularly useful in SDS-PAGE, where they provide clear and sharp bands, aiding in the analysis of protein samples. The 15-well format is ideal for running multiple samples simultaneously, increasing efficiency in laboratories. The 1.5mm thickness ensures sufficient sample loading capacity while maintaining resolution. The glass plate construction provides durability and stability during the electrophoresis process. These gels are commonly used in research, clinical diagnostics, and quality control in biotechnology and pharmaceutical industries. They are also employed in western blotting as the first step in protein detection and characterization. The precast nature of these gels saves preparation time and ensures consistency between experiments, making them a convenient choice for routine protein analysis.
