Patent ID: 7238323

Claim:
A sequencing apparatus comprising: a body having a top portion, a bottom portion and an interior portion; the interior portion comprising at least two intersecting channels, wherein at least one of the two intersecting channels has at least one cross sectional dimension between about 0.1 μm and 500 μm; an electrokinetic fluid direction system for moving a first sequencing reagent through at least one of the two intersecting channels; a source of sequencing primers; an electropipettor for introducing sequencing primers from the source of sequencing primers to the at least two intersecting channels; a mixing zone fluidly connected to the at least two intersecting channels for mixing the first sequencing reagent with a second sequencing reagent; a size separation zone fluidly connected to the mixing zone for separating sequencing products by size, thereby providing the sequence of a target nucleic acid; and a computer having computer-readable code for selecting a sequencing primer.
