    摘要: The present invention utilizes the SELEX (Systematic Evolution of Ligands for EXponential Enrichment) method for identifying and preparing nucleic acid ligands to basic fibroblast growth factor (bFGF) and thrombin. Included in the invention are nucleic acid ligands to bFGF which are inhibitors of bFGF and 2′-amino-modified RNA ligands to bFGF. Further included in the present invention are modified nucleotide sequences to thrombin based on the sequences of the RNA ligands identified. The modified RNA ligands to bFGF and thrombin exhibit increased in vivo stability.

    摘要: A competitive binding assay is used to determine whether a non-nucleic acid molecule from a library of non-nucleic acid molecules binds to a target. The non-nucleic acid molecule competes with a labeled nucleic acid ligand for binding to the target which may be immobilized. Detecting displacement of labeled nucleic acid ligand from a complex of the labeled nucleic acid ligand and the target determines binding of the non-nucleic acid molecule to the target. The nucleic acid ligand may be immobilized and contacted with a labeled target to form a complex. Adding a non-nucleic acid molecule to the complex displaces labeled target from the complex, and detecting displacement of the labeled target determines binding of the non-nucleic acid molecule to the target. Labeled nucleic acid ligand or labeled target displaced from or remaining in the complex can be detected for detecting displacement. Nucleic acid ligands that bind to the target are identified by the SELEX method. The assay provides a high throughput screening method for determining whether a non-nucleic acid molecule binds to a target.
