The term electrophoresis describes the migration of a charged particle in medium (buffer/liquid) under the influence of an electric field.

#Id: 2457

#Unit 13. Methods in Biology

In electrophoresis because of the varying charges and masses, of different molecules and particles of a mixture will migrate at different velocities under uniform force and will thus be separated into single fractions.

When the potential gradient E is applied, the force F on a molecule bearing a charge of Q  sepreated  by distance d (measured in coulombs) is                  (in newton).

If the frictional force taken into the consideration (which depend on hydrodynamic size, shape of the molecule, pore size of the medium, & pore size of the medium) velocity, v , of a charged molecule in an electric field is therefore given by the equation

where f is the frictional coefficient.
