The present invention provides novel compositions, methods and apparatus for DNA sequencing that can be performed, e.g., in a two-electrode chamber. The present invention also provides a method for sequencing a nucleic acid comprising immobilizing a plurality of complexes comprising a target nucleic acid, a primer nucleic acid, and a polymerase onto a surface, contacting the surface with a plurality of charged particles comprising a nucleotide phosphate by applying an electric field, reversing the electric field to transport unbound charged particles away from the surface, and detecting the incorporation of a nucleotide phosphate into a single molecule of the primer nucleic acid.

Method for nucleic acid sequencing

Polymerase-nucleic acid complex

This invention relates to improved methods for sequencing and genotyping nucleic acid in a single molecule configuration. The method involves single molecule detection of fluorescent labeled PPi moieties released from NTPs as a polymerase extension product is created.

System and methods for nucleic acid sequencing of single molecules by polymerase synthesis

Field switch sequencing

Field-switch sequencing

System and method for nucleic acid sequencing by polymerase synthesis

The present invention provides compositions and methods for detecting incorporation of a labeled nucleotide triphosphate onto the growing end of a primer nucleic acid molecule. The method is used, for example, to genotype and sequence a nucleic acid. In a preferred embodiment, the method described herein detects individual NTP molecules.

DNA intercalating agents

The present invention provides compounds, methods and systems for sequencing nucleic acid using single molecule detection. Using labeled NPs that exhibit charge-switching behavior, single-molecule DNA sequencing in a microchannel sorting system is realized. In operation, sequencing products are detected enabling real-time sequencing as successive detectable moieties flow through a detection channel. By electrically sorting charged molecules, the cleaved product molecules are detected in isolation without interference from unincorporated NPs and without illuminating the polymerase-DNA complex.
