PCT No. PCT/US96/06060 Sec. 371 Date Oct. 28, 1997 Sec. 102(e) Date Oct. 28, 1997 PCT Filed May 1, 1996 PCT Pub. No. WO96/34875 PCT Pub. Date Nov. 7, 1996A 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, including cell surface macromolecules. The nucleic acid 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 and the high affinity nucleic acids are amplified for further partitioning. The high affinity nucleic acid ligands are useful in capturing target cells.
