Bis-Tris precast gels are widely used in protein electrophoresis, particularly for separating proteins with high resolution and sharp bands. The 12% concentration is ideal for analyzing a broad range of protein sizes, making it suitable for applications such as Western blotting, protein characterization, and quality control in research and biopharmaceutical industries. The 15-well format allows for multiple samples to be run simultaneously, enhancing efficiency in high-throughput experiments. The 1.5mm thickness ensures sufficient sample loading capacity while maintaining optimal separation. The glass-backed design provides durability and stability during handling and staining processes. These gels are often preferred for their consistent performance, reduced run times, and compatibility with downstream analysis techniques.
