Abstract: This invention provides methods for purifying nucleic acids, in particular primer extension products such as those obtained in nucleic acid sequencing reactions. The methods involve the use of a primer to which is attached a string of arylboronic acid moieties. After extension of the primer using a polymerase, the primer extension products are complexed with a solid support to which is attached an arylboronic acid complexing moiety. The resulting complex is separated from the reaction mixture, washed, and the primer extension products are dissociated from the solid support. The primer extension products are obtained in a form particularly suitable for loading directly on a capillary electrophoresis apparatus.
