High affinity nucleic acid ligands of ICP4
First Claim
Patent Images
1. A method of identifying nucleic acid ligands to an ICP4 protein family member, comprising:
- a) preparing a candidate mixture of nucleic acids;
b) contacting the candidate mixture of nucleic acids with an ICP4 protein family member, wherein nucleic acids having an increased affinity to an ICP4 protein family member 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; and
d) amplifying the increased affinity nucleic acids to yield a mixture of nucleic acids enriched for nucleic acid sequences with relatively higher affinity and specificity for binding an ICP4 protein family member, wherein nucleic acid ligands of an ICP4 protein family member may be identified.
