Key Concepts of Gel Electrophoresis: Principle: Charged molecules migrate through an agarose or polyacrylamide gel matrix under an electric field. Separation: Smaller molecules move faster and travel farther than larger ones. Visualization
No bands visible: Check if the power supply is functioning, staining solution is effective, and samples contain DNA. Bands migrating irregularly: Ensure the gel is evenly poured and that the buffer is fresh and at correct pH. Safety and Ethical Considerations Handling Hazardous Chemicals Use
