The Prestained Protein Ladder (10-180kDa) is widely used in molecular biology and biochemistry laboratories for protein analysis. It serves as a reference marker in SDS-PAGE (Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis) to estimate the molecular weights of unknown proteins. The prestained bands allow researchers to visually monitor the progress of electrophoresis in real-time, ensuring accurate separation and migration of proteins. This ladder is particularly useful for Western blotting, as the colored bands help in aligning the transfer membrane and confirming successful protein transfer. It is also employed in routine protein research, quality control, and validation of experimental results, providing a reliable and consistent standard for protein size determination.
