Paper Abstract

A laser-excited, confocal-fluorescence scanner is used for high-sensitivity, on-column detection of electrophoresis performed using an array of capillaries. The capabilities of this method and apparatus are illustrated by application to high-speed, high-throughput DNA sequencing. Sanger DNA sequencing fragments are separated on an array of capillaries and then distinguished by using a binary coding scheme that employs only two different fluorescently labeled dye primers to identify four sets of fragments. DNA sequencing results are presented using a 25-capillary array. This apparatus has the capability of sequencing DNA at a rate of approximately 25,000 bases/hour.
