What is the Purpose of Running a Gel After Electrophoresis?
Electrophoresis is a laboratory technique used to separate molecules based on their size and electrical properties. After electrophoresis, a gel is run to visualize and analyze the separated molecules. The purpose of running a gel is to:
- Confirm Electrophoresis Results: The gel provides a physical representation of the separation, allowing researchers to verify the electrophoresis process and ensure that the molecules were separated as expected.
- Measure Molecular Size: By comparing the distance that the molecules traveled in the gel to a known molecular ladder, researchers can determine the size of the unknown molecules.
- Identify Specific Molecules: Some gels contain fluorescent or radioactive dyes that bind to specific molecules. This allows researchers to identify and quantify the presence of specific molecules in the sample.
- Isolate DNA or RNA Fragments: Gels can be used to isolate DNA or RNA fragments of specific sizes. This is useful for further analysis, such as sequencing or cloning.
- Determine Molecular Interactions: Gels can also be used to study molecular interactions, such as protein-protein or protein-DNA binding. By analyzing the interactions between molecules on the gel, researchers can gain insights into their functions and relationships.
