DNA sequencing by capillary array electrophoresis and microfabricated array systems

To comply with the current needs for high-speed DNA sequencing analysis, several instruments and innovative technologies have been introduced by several groups in recent years. This review article discusses and compares the issues regarding high-throughput DNA sequencing by electrophoretic methods in miniaturized systems, such as capillaries, capillary arrays, and microchannels. Initially, general features of several capillary array designs (including commercial ones) will be considered, followed by similar analyses with microfabricated array electrophoretic devices and how they can contribute to the success of large sequencing projects.
