Study Notes
Agarose Gel Electrophoresis
- A method of gel electrophoresis used in molecular biology, genetics, and clinical chemistry to separate macromolecules such as DNA, RNA, or proteins.
- Uses a matrix of agarose, a natural linear polysaccharide extracted from seaweed.
Principle of Electrophoresis
- Separation based on electrophoretic charge, which depends on the extra functional group on the surface of biomolecules.
- Biomolecules exist as electrically charged particles with either positive or negative charges.
- In an electric field, charged molecules travel to the opposite direction of the positive or negative pole.
- Molecules migrate at different rates depending on their mass, not their charge, when exposed to an electric field.
