Methods for identifying nucleic acid ligands

摘要

The SELEX (Systematic Evolution of Ligands by EXponential Enrichment) method is disclosed for the identification of nucleic acid ligands. A candidate mixture of single stranded nucleic acids having regions of randomized sequence is contacted with a target compound and those nucleic acids having an increased affinity to the target are partitioned from the remainder of the candidate mixture. The partitioned nucleic acids are amplified to yield a ligand enriched mixture.
