GLOSSARY: Electrophoresis

Electrophoresis is defined as the migration of electrically charged proteins, colloids, molecules, or other particles when dissolved or suspended in an electrolyte through which an electric current is passed. The most important use of electrophoresis is in the analysis of blood proteins. Since the proportion of these proteins varies widely in different diseases, electrophoresis can be used for diagnostic purposes. Electrophoresis is used to study bacteria and viruses, nucleic acids, and some types of smaller molecules, including amino acids.
