Abstract

Aspects of the disclosure provide biconjugatable labels, labeled biomolecules, and methods of using and making the same.

Claims (20)

1. A labeled biomolecule of the formula:

wherein:

Q 1 and Q 2 are independently monomeric or oligomeric biomolecules;

L 1 and L 2 are independently optionally substituted alkylene; and

X − is a counterion or is absent.

2. The labeled biomolecule of claim 1 , wherein Q 1 and Q 2 are independently nucleosides, nucleotides, oligonucleotides, nucleic acids, or derivatives or fragments thereof.

3. The labeled biomolecule of claim 2 , wherein Q 1 and/or Q 2 form a first oligonucleotide strand.

4. The labeled biomolecule of claim 3 , further comprising a second oligonucleotide strand hybridized to the first oligonucleotide strand.

5. The labeled biomolecule of claim 1 , wherein a nucleoside polyphosphate is attached through a terminal phosphate to Q 1 and/or Q 2 .

6. The labeled biomolecule of claim 1 , wherein the labeled biomolecule is of the formula:

wherein n is independently an integer from 1-20, inclusive.

7. The labeled biomolecule of claim 6 , wherein the labeled biomolecule is of the formula:

8. The labeled biomolecule of claim 7 , wherein the labeled biomolecule is of the formula:

9. The labeled biomolecule of claim 1 , wherein L 1 and L 2 are independently optionally substituted C 1-20 alkylene.

10. The labeled biomolecule of claim 9 , wherein L 1 and L 2 are independently optionally substituted C 1-10 alkylene.

11. The labeled biomolecule of claim 3 , wherein the first oligonucleotide strand comprises at least 10 and fewer than 200 nucleotides.

12. The labeled biomolecule of claim 11 , wherein the first oligonucleotide strand comprises at least 10 and fewer than 100 nucleotides.

13. The labeled biomolecule of claim 12 , wherein the first oligonucleotide strand comprises at least 10 and fewer than 50 nucleotides.

14. The labeled biomolecule of claim 1 , wherein Q 1 and Q 2 are independently oligonucleotides, nucleic acids, or derivatives or fragments thereof, and wherein Q 1 and Q 2 form a first oligonucleotide strand.

15. The labeled biomolecule of claim 14 , further comprising a second oligonucleotide strand hybridized to the first oligonucleotide strand.
