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 a broad range of proteins, particularly those with medium to high molecular weights. These gels are commonly applied in research and diagnostic labs for analyzing protein samples, such as in Western blotting, SDS-PAGE, and other protein separation techniques. The 11-well format allows for multiple samples to be run simultaneously, enhancing efficiency. The 1.0mm thickness ensures consistent resolution and minimizes handling risks. The plastic backing provides durability and ease of handling during staining and transfer processes. These gels are particularly valued for their reproducibility, convenience, and time-saving features compared to traditional hand-cast gels.
