Methods for identifying nucleic acid ligands
First Claim
Patent Images
1. A method for identifying nucleic acid ligands of a target compound from a candidate mixture comprised of single stranded nucleic acids each having a region of randomized sequence, said, method comprising:
- a) contacting the candidate mixture with the target, wherein nucleic acids having an increased affinity to the target relative to the candidate mixture may be partitioned from the remainder of the candidate mixture;
b) partitioning the increased affinity nucleic acids from the remainder of the candidate mixture; and
c) amplifying the increased affinity nucleic acids, in vitro, to yield a ligand-enriched mixture of nucleic acids, whereby nucleic acid ligands of the target compound may be identified.

Abstract
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.
