Different types of electrophoresis?

1. Gel electrophoresis: This is the most common type of electrophoresis, where DNA, RNA, or proteins are separated based on their size and charge by running them through a gel matrix.

2. Capillary electrophoresis: In this technique, the separation of molecules is done in a capillary tube filled with a buffer solution. It is often used for DNA sequencing and analysis of small molecules.

3. Isoelectric focusing: This method separates proteins based on their isoelectric point, which is the pH at which a protein has no net charge. Proteins are separated in a gel based on their charge at a specific pH gradient.

4. Pulse field gel electrophoresis: This technique is used to separate large DNA fragments, such as whole chromosomes, by applying alternating electric fields in different directions to improve resolution.

5. Affinity electrophoresis: This method separates molecules based on their specific binding affinity to a ligand that is immobilized on the gel matrix.

6. Two-dimensional gel electrophoresis: This technique combines two different separation methods, usually isoelectric focusing and SDS-PAGE, to achieve higher resolution and better separation of complex mixtures of proteins.
