Bis-Tris precast gels are widely used in protein electrophoresis for separating proteins based on their molecular weight. The 6% concentration is ideal for resolving high molecular weight proteins, making it suitable for applications in biochemistry and molecular biology research. These gels provide consistent and reproducible results, reducing the need for gel preparation time. The 15-well format allows for multiple samples to be run simultaneously, enhancing throughput in experiments. The 1.5mm thickness ensures sufficient sample loading capacity while maintaining resolution. Glass plates provide durability and clarity, facilitating easy visualization of protein bands during analysis. These gels are commonly used in studies involving protein characterization, quality control, and biomarker discovery.
