    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.
