Bis-Tris precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 15% concentration is ideal for resolving small to medium-sized proteins, typically in the range of 10-200 kDa. The 1.5mm thickness ensures sufficient sample loading capacity while maintaining sharp resolution. These gels are particularly favored for their stability and consistent performance in SDS-PAGE, reducing the risk of protein degradation or diffusion during the separation process. The 10-well format allows for multiple samples to be run simultaneously, making it efficient for comparative analysis, such as in protein expression studies or quality control in biopharmaceutical production. The glass backing provides durability and ease of handling, minimizing the risk of breakage during transfer or staining procedures. Bis-Tris gels are also compatible with various staining methods, including Coomassie Blue and silver staining, as well as Western blotting applications, ensuring versatility in downstream analysis. Their precast nature saves time and eliminates the variability associated with manually casting gels, making them a reliable choice for high-throughput laboratories.
