- (biotechnology) The technique of separating charged molecules in a matrix to which is applied an electrical field.
- (chemistry) A technique for separation of ions by rate and direction of migration in an electric field.
- (genetics) Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. An electric current is used to move molecules to be separated through a gel. Pores in the gel work like a sieve, allowing smaller molecules to move faster than larger molecules. The conditions used during electrophoresis can be adjusted to separate molecules in a desired size range.
