Electrophoresis is a separations technique that is based on the the mobility of ions in an electric field.This is the main technique for molecular separation in today's cell biology laboratory.

The positively charged ions migrate towards a negative electrode and negatively-charged ions migrate toward a positive electrode.For safety reasons one electrode is usually at ground and the other is biased positively or negatively. Ions have different migration rates depending on their total charge, size, and shape, and can therefore be separated.

We hope that clarifies your query.
