Tris-Glycine precast gels are widely used in molecular biology and biochemistry laboratories for protein separation and analysis. They are particularly effective for SDS-PAGE (Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis), a technique used to separate proteins based on their molecular weight. The 4-12% gradient allows for the resolution of a broad range of protein sizes, making it suitable for analyzing complex protein mixtures. The 15-well format is ideal for running multiple samples simultaneously, enhancing efficiency in high-throughput experiments. The 1.5mm thickness ensures sufficient sample loading capacity while maintaining sharp band resolution. Glass plates provide durability and stability during the electrophoresis process. These gels are commonly used in applications such as protein purification, Western blotting, and protein characterization, offering consistent and reliable results for researchers.
