SINGLE MOLECULE SEQUENCING METHOD

摘要

The invention relates to a method for single molecule sequencing of nucleic acids that comprises the following steps: a) providing a support particle with a nucleic acid molecule immobilized thereon, substantially all nucleotide components of at least one base type in at least one strand of the nucleic acid molecule carrying a fluorescent label, b) introducing the support particle into a microchannel sequencing device, c) retaining the support particle in the sequencing device, d) progressively cleaving individual nucleotide components from the immobilized nucleic acid molecule, e) guiding the cleaved off nucleotide components through a microchannel by means of a hydrodynamic flow, and f) identifying the base sequence of the nucleic acid molecule by the order of the cleaved off nucleotide components. The invention also relates to a device for carrying out the inventive method.
