Bis-Tris precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 8% gel concentration is particularly suitable for resolving medium to high molecular weight proteins, making it ideal for applications such as Western blotting, protein characterization, and quality control in biotechnology and pharmaceutical research. The 15-well format allows for multiple samples to be run simultaneously, enhancing throughput and efficiency. The 1.5mm thickness ensures optimal resolution and sample loading capacity, while the glass plate construction provides durability and stability during electrophoresis. These gels are compatible with various staining techniques and downstream analysis methods, offering reliable and reproducible results for researchers.
