Abstract

A chlorotoxin conjugate detectable by fluorescence imaging that allows for intra-operative visualization of cancerous tissues, compositions that include the chlorotoxin conjugate, and methods for using the chlorotoxin conjugate.

Claims (14)

1. A chlorotoxin conjugate, comprising a cyanine moiety covalently coupled to a chlorotoxin.

2. The conjugate of claim 1 , wherein the chlorotoxin is selected from the group consisting of native chlorotoxin, synthetic chlorotoxin, and recombinant chlorotoxin.

3. The conjugate of claim 1 , wherein the conjugate comprises from one to three cyanine moieties covalently coupled to the chlorotoxin.

4. A chlorotoxin conjugate, consisting of from one to three cyanine moieties covalently coupled to a chlorotoxin.

5. The conjugate of claim 4 , wherein the chlorotoxin is selected from the group consisting of native chlorotoxin, synthetic chlorotoxin, and recombinant chlorotoxin.

6. A chlorotoxin conjugate, consisting of a cyanine moiety covalently coupled to a chlorotoxin.

7. The conjugate of claim 6 , wherein the chlorotoxin is selected from the group consisting of native chlorotoxin, synthetic chlorotoxin, and recombinant chlorotoxin.

8. A composition, comprising a pharmaceutically acceptable carrier and a chlorotoxin conjugate, wherein the conjugate comprises a cyanine moiety covalently coupled to a chlorotoxin.

9. The composition of claim 8 , wherein the chlorotoxin is selected from the group consisting of native chlorotoxin, synthetic chlorotoxin, and recombinant chlorotoxin.

10. The composition of claim 8 , wherein the conjugate comprises from one to three cyanine moieties.

11. A composition, comprising a pharmaceutically acceptable carrier and a chlorotoxin conjugate, wherein the conjugate consists of from one to three cyanine moieties covalently coupled to a chlorotoxin.

12. The composition of claim 11 , wherein the chlorotoxin is selected from the group consisting of native chlorotoxin, synthetic chlorotoxin, and recombinant chlorotoxin.

13. A composition, comprising a pharmaceutically acceptable carrier and a chlorotoxin conjugate, wherein the conjugate consists of a cyanine moiety covalently coupled to a chlorotoxin.

14. The composition of claim 13 , wherein the chlorotoxin is selected from the group consisting of native chlorotoxin, synthetic chlorotoxin, and recombinant chlorotoxin.
