Two-dimensional gene scanning (TDGS) is a method for mutation detection based on two-dimensional electrophoretic separation of PCR-amplified DNA fragments according to size and base pair sequence. To facilitate two-dimensional electrophoresis without manual interference, a simple three-chamber unit was designed on top of an existing vertical electrophoresis instrument. Application of this system to genetic testing is demonstrated by the performance of a complete two-dimensional mutational scanning assay of one of the hereditary nonpolyposis colon cancer syndrome susceptibility genes, hMLH1.
