WebCharged molecules move through a gel when an electric current is passed across it. An electric current is applied across the gel so that one end of the gel has a positive charge and the other end has a negative charge. Molecules migrate towards the opposite charge. A molecule with a negative charge will therefore be pulled towards the positive end.
