Abstract
Nonporous polymer beads having an average diameter of about 1-100 microns are suitable for chromatographic separation of mixtures of nucleic acids when the polymer beads are alkylated with alkyl chains having at least three carbon atoms. The polymer beads provide efficient separation of nucleic acids using ion-pair reverse phase chromatography.
