Details for Patent: 6,544,959

Title: High affinity nucleic acid ligands to lectins
Abstract:This invention discloses high-affinity oligonucleotide ligands to lectins, specifically nucleic acid ligands having the ability to bind to the lectins, wheat germ agglutinin, L-selectin, E-selectin and P-selectin. Also disclosed are the methods for obtaining such ligands.
Inventor(s): Parma; David H (Boulder, CO), Hicke; Brian (Boulder, CO), Bridonneau; Philippe (Boulder, CO), Gold; Larry (Boulder, CO)
Assignee: Gilead Sciences, Inc. (Foster City, CA)
Filing Date:May 04, 2001
Application Number:09/849,928
Claims:1. A method for treating a lectin-mediated disease comprising administering a pharmaceutically effective amount of a nucleic acid ligand to a lectin.

2. The method of claim 1 wherein said nucleic acid ligand to a lectin is identified according to a method comprising: a) contacting a candidate mixture of nucleic acids with a lectin, wherein nucleic acids having an increased affinity to said lectin relative to the candidate mixture may be partitioned from the remainder of the candidate mixture; b) partitioning the increased affinity nucleic acids from the remainder of the candidate mixture; and c) amplifying the increased affinity nucleic acids to yield a mixture of nucleic acids enriched for nucleic acid sequences with relatively higher affinity and specificity for binding said lectin, whereby nucleic acid ligands of said lectin may be identified.

3. The method of claim 1 wherein said lectin is a selectin.

4. The method of claim 3 wherein said selectin is L-selectin.

5. The method of claim 3 wherein said selectin is P-selectin.

6. The method of claim 4 wherein said nucleic acid ligand to a lectin is selected from the group consisting of SEQ ID NO: 67-117, 129-196, and 293-388.

7. The method of claim 5 wherein said nucleic acid ligand to a lectin is selected from the group consisting of SEQ ID NO: 199-247, and 251-290.
