How can I optimize the resolution and separation of proteins on a 12 SDS-PAGE gel for my experiment?

To optimize resolution and separation of proteins on a 12 SDS-PAGE gel, you can adjust factors like the percentage of acrylamide in the gel, the running buffer pH, and the running time. Increasing the acrylamide percentage can improve resolution for smaller proteins, while decreasing it can help separate larger proteins. Adjusting the running buffer pH can also impact separation, with a slightly acidic pH often yielding better results. Lastly, running the gel for a longer time can enhance resolution for closely sized proteins.
