Tris-Glycine Precast Gel (15%, 15 wells, 1.5mm, Glass) is widely used in molecular biology and biochemistry laboratories for protein separation and analysis. Its primary application is in SDS-PAGE (Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis), a technique used to separate proteins based on their molecular weight. The 15% polyacrylamide concentration is ideal for resolving small to medium-sized proteins, typically in the range of 10-150 kDa. The gel is precast, ensuring consistency, convenience, and time-saving, as researchers do not need to prepare gels manually. The 15-well format allows for multiple samples to be run simultaneously, making it suitable for comparative studies or high-throughput applications. The 1.5mm thickness provides sufficient sample loading capacity while maintaining sharp resolution during electrophoresis. This gel is commonly used in applications such as protein purity assessment, molecular weight determination, and immunoblotting (Western blotting). It is compatible with downstream processes like protein transfer to membranes for antibody-based detection. Its glass-backed design ensures durability and easy handling during experimental procedures. Overall, it is a reliable tool for protein analysis in research, diagnostics, and quality control.
