Bis-Tris precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 4-12% gradient allows for effective resolution of a broad range of protein sizes, making it suitable for analyzing complex protein mixtures. The 10-well format is ideal for comparing multiple samples simultaneously, while the 1.5mm thickness ensures sufficient sample loading capacity and sharp band resolution. The glass plate construction provides durability and stability during electrophoresis runs. These gels are commonly used in research labs for applications such as western blotting, protein purification, and quality control in biotechnology and pharmaceutical industries. Their precast nature saves time and ensures consistent performance, making them a reliable choice for protein analysis.
