|Assignee:||Gilead Sciences, Inc. (Foster City, CA)|
|Filing Date:||Dec 18, 2001|
|Claims:||1. A method for detecting a site of deep vein thrombosis in an individual, the method comprising: (a) providing a nucleic acid ligand to a .alpha..sub.v.beta..sub.3 or .alpha..sub.IIb.beta..sub.3 mtegrm dimer, wherein said ligand binds to a nucleic acid binding site in said integrin .beta..sub.3 and said nucleic acid ligand conjugated to a radioactive label and wherein said nucleic acid ligand is selected from Table 1, 2 or 3; (b) administering said nucleic acid ligand to said individual; (c) detecting the site of said thrombosis by analyzing the localization of said nucleic acid ligand using a radioimaging technique. |
2. A clot-detection composition comprising a nucleic acid ligand to a .alpha..sub.v.beta..sub.3 or .alpha..sub.IIb.beta..sub.3 integrin and a pharmaceutically-acceptable excipient, wherein said ligand binds to a nucleic acid binding site in said integrin .beta..sub.3 and wherein said nucleic acid ligand is selected from Table 1, 2 or 3.
