Method for preparing polynucleotide sequences and uses thereof

摘要

Methods are described for the preparation of quantities of preselected polynucleotide sequences in purified form. The method is independent of length or sequence, and can be used to prepare multi-milligram quantities of, for example, single length, isotope-enriched duplex DNA following a single-step chromatographic purification of the desired product. The method of the present invention allows for preparative scale synthesis of DNA yielding a single product length. The application of the method to NMR spectroscopy of DNA provides the opportunity to identify biologically relevant interactions between polynucleotide sequences and other macromolecules, and assist in the identification and development of agents having therapeutic utility as a consequence of the promotion or antagonism of these interactions.
