摘要:
Nucleotide triphosphate probes containing a fluorophore attached to the &ggr;-phosphate and a quencher moiety sufficiently proximal to the fluorophore moiety for use in pyrophosphate detection assays are disclosed. These probes exhibit distinguishable fluorescence characteristics when the fluorophore is attached to the nucleotide through the &ggr;-phosphate and when it is unattached to the nucleotide. The present invention also provides kits and integrated systems for practicing the assays described herein.

摘要:
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.
