Nucleic acid ligands which bind to hepatocyte growth factor/scatter factor (HGF/SF) or its receptor c-met
First Claim
Patent Images
1. A method for the isolation of nucleic acid ligands to HGF, comprising:
- a) preparing a candidate mixture of nucleic acids;
b) contacting the candidate mixture of nucleic acids with HGF, wherein nucleic acids having an increased affinity to HGF relative to the candidate mixture may be partitioned from the remainder of the candidate mixture;
c) partitioning the increased affinity nucleic acids from the remainder of the candidate mixture;
d) amplifying the increased affinity nucleic acids to yield a mixture of nucleic acids enriched for nucleic acids with relatively higher affinity and specificity for binding to HGF, whereby a nucleic acid ligand of HGF may be identified.

Abstract
The invention provides nucleic acid ligands to hepatocyte growth factor/scatter factor (HGF) and its receptor c-met. The nucleic acid ligands of the instant invention are isolated using the SELEX method. SELEX is an acronym for Systematic Evolution of Ligands by EXponential enrichment. The nucleic acid ligands of the invention are useful as diagnostic and therapeutic agents for diseases in which elevated HGF and c-met activity are causative factors.
