[英文释义] Electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However,by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length.
