Nucleic acid affinity columns

Abstract

Nucleic acid affinity matrices that bear a large number of different nucleic acid affinity ligands allowing the simultaneous selection and removal of a large number of preselected nucleic acids from the sample. Methods of producing such affinity matrices are also provided. In general the methods involve the steps of a) providing a nucleic acid amplification template array comprising a surface to which are attached at least 50 oligonucleotides having different nucleic acid sequences, and wherein each different oligonucleotide is localized in a predetermined region of the surface, the density of the oligonucleotides is greater than about 60 different oligonucleotides per 1 cm2, and all of the different oligonucleotides have an identical terminal 3′ nucleic acid sequence and an identical terminal 5′ nucleic acid sequence. b) amplifying the multiplicity of oligonucleotides to provide a pool of amplified nucleic acids; and c) attaching the pool of nucleic acids to a solid support.
