MICROSEQUENCER-WHOLE GENOME SEQUENCER

摘要

The method and apparatus are disclosed to support speedy sequencing of genomes of individuals. The method comprises random digestion of a stretch of DNA; adaptor ligation of adaptor DNA fragments to DNA segments produced in random digestion, each said adaptor DNA fragment containing a sequence which is complementary to a single DNA primer; PCR amplification of the ligated segments produced in adaptor ligation, utilizing a single DNA primer; distributing the ligated segments into one or more pre-defined isolated locations of a sequencing apparatus, each said location containing DNA fragments placed there for capturing a unique kind of digested DNA segments; capturing at each location a unique kind of amplified DNA segments by hybridization with the DNA fragments; dislodging captured DNA segments from DNA fragments; adding DNA sequencing reaction components into the locations; performing sequencing reactions at each location; separating the products of the sequencing reactions in the sequencing apparatus; and determining the sequences of DNA segments captured at individual locations of the sequencing apparatus. The apparatus comprises one or more isolated locations, each location has a reservoir containing DNA fragments placed there for capturing a unique kind of DNA segments from a DNA solution after dispensing the DNA solution into the reservoir; one or more channels performing DNA separation according to size, said channels being associated with one or more reservoirs; one or more gates controlling the flow of substances in the reservoirs; an optical system which induces fluorescence excitation in, and detects fluorescence emission in the channels; and a computer to produce DNA sequence data.
