Bis-Tris precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 12% concentration is ideal for resolving proteins in the mid-range molecular weight, making it suitable for various biological and biochemical studies. The 10-well format allows for multiple samples to be run simultaneously, enhancing efficiency in experiments. The 1.5mm thickness ensures sufficient sample loading capacity while maintaining sharp resolution. The glass backing provides durability and stability during handling and staining processes. These gels are commonly employed in research labs for applications such as protein purity analysis, molecular weight determination, and studying protein-protein interactions. Their precast nature saves time and ensures consistent performance, making them a convenient choice for routine protein analysis.
