摘要:
A new class of nucleic acid compounds, referred to as nucleic acid ligands, have been shown to exist that have a specific binding affinity for three dimensional molecular targets. In a preferred embodiment the ligands are identified by the method of the invention referred to as the Systematic Evolution of Ligands by EXponential enrichment (SELEX), wherein a candidate mixture of nucleic acids are iteratively enriched in high affinity nucleic acids and amplified for further partitioning.
摘要:
A method is described for generating blended nucleic acid ligands containing non-nucleic acid functional units. Specifically, a SELEX identified RNA ligand to the integrin gpIIbIIIa is conjugated to the peptide Gly-Arg-Gly-Asp-Thr-Pro (SEQ ID NO:1). This blended RNA ligand inhibits the biological activity of gpIIbIIIa with high specificity. Also described is a single-stranded DNA ligand to elastase coupled to N-methoxysuccinyl-Ala-Ala-Pro-Val-chloromethyl (SEQ ID NO:2) ketone. This elastase blended nucleic acid ligand inhibits the biological activity of elastase.
