Abstract

A compound having the general formula shown below:

where R_1-6 are independently selected from the group consisting of an electron withdrawing group, an alkyl group, an aryl group, hydrogen, a heteroaryl group, and a five or six member ring structure formed from the R₁ and R₂ pair, the R₃ and R₄ pair, the R₄ and R₅ pair, or the R₅ and R₆ pair; R₇ is a substituted or unsubstituted aryl group; and Y is a nucleophile.

Claims

1. A composition comprising a reporter moiety linked to an oligonucleotide through an oxime bond.

2. The composition of claim 1, wherein the reporter moiety is either a fluorophore or a quencher.

3. The composition of claim 1, wherein the reporter moiety is a compound of Formula (I)

4. The composition of claim 2, wherein the reporter moiety is

5. The composition of claim 1, wherein the oligonucleotide is linked to a solid support at its 3′

end.

6. The composition of claim 1, wherein the reporter moiety is linked to a 3′

end of the oligonucleotide.

7. The composition of claim 1, wherein the reporter moiety is linked to a 5′

end of the oligonucleotide.

8. The composition of claim 1, wherein the reporter moiety is linked to an internal nucleotide.

9. The composition of claim 1, further wherein the reporter moiety is a first reporter moiety, and further comprising a second reporter moiety linked to the oligonucleotide.

10. The composition of claim 9, wherein one of the first and second reporter moieties is a fluorophore and the other of the first and second reporter moieties is a quencher.

11. A kit comprising the composition of claim 1.

12. The kit of claim 1, further comprising instructions for the use of the composition.
