Abstract

Nucleosides and nucleotides are disclosed that are linked to detectable labels via a cleavable linker group.

Claims

1. A method for controlling the incorporation of nucleotides into a polynucleotide strand, comprising the steps of:

(a) providing a nucleotide having a ribose or deoxyribose sugar moiety, wherein an enzymatically removable protecting group is attached to the 3′

or the 2′

oxygen atom of the ribose or deoxyribose sugar moiety of the nucleotide;

(b) providing a first enzyme to incorporate the nucleotide into the strand, whereby the protecting group prevents incorporation of another nucleotide into the strand, and detecting the incorporated nucleotide; and

(c) providing a second enzyme to remove the protecting group to expose a 3′

-OH group on the first nucleotide, thereby allowing incorporation of another nucleotide into the strand;

(d) repeating steps (a) to (c) at least once;

thereby controlling the incorporation of nucleotides into the strand;

wherein the protecting group comprises a disulfide.

2. The method of claim 1, wherein the enzymatically removable protecting group is attached to the 3′

oxygen atom of the ribose or deoxyribose sugar moiety of the nucleotide.

3. The method of claim 1, wherein the enzymatically removable protecting group is attached to the 2′

oxygen atom of the ribose or deoxyribose sugar moiety of the nucleotide.

4. The method of claim 1, wherein the first enzyme is engineered to incorporate the protected nucleotide into the strand.

5. The method of claim 1, wherein the first enzyme is a polymerase.

6. The method of claim 5, wherein the polymerase is Klenow exo.

7. The method of claim 1, wherein the first enzyme is a terminal transferase or a reverse transcriptase.

8. The method of claim 1, wherein the base of the nucleotide is a deazapurine.

9. The method of claim 1, wherein the nucleotide is detected by a detectable label.

10. The method of claim 9, wherein the detectable label is a fluorophore.

11. The method of claim 10, wherein the detectable label is part of a FRET system.

12. The method of claim 1, wherein the detection is carried out with the polynucleotide on a solid support.
