Resolution of DNA fragments by pulsed field gradient gel electrophoresis is a function of the pulse time, geometry, and strength of the orthogonal electric fields. The first field geometry described had a number of disadvantages. We show that these disadvantages can be largely overcome by a modified electric field geometry together with an altered switch pattern. These changes are shown to have critical consequences for the technique. Resolution is more uniform across the gel, which permits more samples to be analyzed on the same gel. In addition, DNA molecules follow a migration path that is approximately straight down the gel. This aspect also increases the number of usable wells. One important property of the system described here provides some insight into the mechanism whereby DNA molecules are resolved by this method.
