Abstract
The needs for purified nucleic acids for preparative and analytical applications have increased
constantly, demanding for the development of new and more efficient methods for their recovery and
isolation. DNA molecules harbour some intrinsic chemical properties that render them suitable for
chromatographic separations. These include a negatively charged phosphate backbone as well as a hydrophobic
character originating mainly from the major groove of DNA which exposes the base pairs on
the surface of the molecule. In addition, single stranded DNA often allows for a free exposure of the hydrophobic
aromatic bases. In this review, multimodal chromatography (MMC) has been evaluated as an
alternative tool for complex separations of nucleic acids. MMC embraces more than one kind of interaction
between the chromatographic ligand and the target molecules. These resins have often proved superior
to conventional single-mode chromatographic materials for DNA isolation, including, e.g., the purification
of plasmid DNA from crude cell lysates and for the preparation of DNA fragments before or
after a polymerase chain reaction (PCR).
