ABSTRACT:
This invention generally relates the generation of aptamers and to the use of aptamers as diagnostic and therapeutic agents. More particularly, the present invention relates to methods using combinatorial chemistry to prepare aptamers having controlled thiophosphate replacement in the phosphate backbone for improved binding efficiencies to a target and to RNA and/or DNA products having novel nucleotide sequences and enhanced target binding efficacies.
