Nucleic acid ligand complexes
First Claim
1. A therapeutic or diagnostic Complex comprised of a Nucleic Acid Ligand and a polyethylene glycol (PEG), wherein said Nucleic Acid Ligand is covalently linked to said PEG, and wherein said Nucleic Acid Ligand has a specific binding affinity for a Target Molecule, said Target Molecule being a three dimensional chemical structure other than a polynucleotide that binds to said Nucleic Acid Ligand through a mechanism which predominantly depends on Watson/Crick base pairing or triple helix binding, wherein said Nucleic Acid Ligand is not a Nucleic Acid having the known physiological function of being bound by the Target Molecule, wherein said PEG is at least about 1000 Daltons, and wherein said Complex has improved pharmacokinetic properties relative to the pharmacokinetic properties of the Nucleic Acid Ligand alone.

Abstract
This invention discloses a method for preparing a therapeutic or diagnostic complex comprised of a nucleic acid ligand and a lipophilic compound or non-immunogenic, high molecular weight compound by identifying a nucleic acid ligand by SELEX methodology and associating the nucleic acid ligand with a lipophilic compound or a non-immunogenic, high molecular weight compound. The invention further discloses complexes comprising one or more nucleic acid ligands in association with a lipophilic compound or non-immunogenic, high molecular weight compound.
