| 摘要 |
The present invention relates to a dual-labeled nucleotide comprising a fluorescent label and a quencher of that fluorescent label, wherein the quencher is attached to a phosphate moiety that is cleaved off when the nucleotide is enzymatically incorporated into a polynucleotide. The invention further relates to methods of labeling a polynucleotide molecule, as well as methods for identifying one or more residues of a polynucleotide using the dual-labeled nucleotide analogs of the present invention and kits comprising dual-labeled nucleotide analogs according to the invention.
