Large-scale microfabricated channel plates for high-throughput, fully automated DNA sequencing.

We have described a new DNA sequencing platform based on the Sanger chemistry, in which the large-scale microfabricated channel plates and electrophoretic system result in higher-throughput DNA sequencing. Three hundred and eighty-four channels are arranged in a fan-like shape on a 25x47 cm glass plate, on which 384 oval sample holes are connected to each channel coupled to the opposite anode access holes. Two microfabricated plates are set on the sequencing apparatus, in which sequencing electrophoresis is conducted on one plate and the preparation process is on another plate.
