Tris-Glycine precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 4-15% gradient allows for a broad range of protein sizes to be resolved efficiently, making it suitable for analyzing complex protein mixtures. These gels are particularly useful in applications such as Western blotting, where precise separation of proteins is critical for accurate identification and quantification. The 10-well format provides multiple lanes for running samples simultaneously, enhancing throughput and consistency. The 1.5mm thickness ensures optimal protein loading capacity and resolution, while the glass plate construction offers durability and stability during electrophoresis. These gels are commonly employed in molecular biology, biochemistry, and clinical research for studying protein expression, purification, and characterization.
