Tris-Glycine Precast Gel (12%, 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 12% gel concentration is optimal for resolving proteins in the mid-range molecular weight, making it suitable for analyzing complex protein mixtures. This gel is particularly useful for applications such as protein purity assessment, molecular weight determination, and preparation for downstream techniques like Western blotting. The 15-well format allows for multiple samples to be run simultaneously, enhancing efficiency in high-throughput experiments. The 1.5mm thickness ensures sufficient protein loading capacity while maintaining clear resolution of separated bands. The glass plate construction provides durability and stability during electrophoresis, ensuring consistent and reliable results. Its precast nature saves time and reduces variability compared to manually cast gels, making it a convenient choice for researchers.
