Electrophoresis

noun

1. The migration of charged colloidal particles or molecules through a stationary medium under the influence of an applied electric field usually provided by immersed electrodes.
2. A method of separating substances, especially proteins, and analyzing molecular structure based on the rate of movement of each component in a colloidal suspension while under the influence of an electric field.
3. the motion of charged molecules or particles in a liquid medium under the influence of an electric field; particles with a positive charge move toward the cathode and negative to the anode.
4. the application of the principle of electrophoresis to separate molecules, used as an analytical or preparative technique.

   "separation by electrophoresis; gel electrophoresis"

5. the migration of electrically charged molecules through a medium under the influence of an electric field
