Abstract

The invention provides an improved method for the purification of nucleic acid molecules, which method comprises generating a cellular lysate containing the nucleic acid; contacting the lysate with an anion exchanger bound to a solid support matrix under conditions such that the anion exchanger binds the nucleic acid; followed by eluting the nucleic acid from the anion exchanger with an aqueous mobile phase comprising an elution solution; and desalting the eluted nucleic acid such that it is suitable for downstream applications. The improvement of the method includes adding in the elution solution a composition such that the pH of the aqueous mobile phase is between about pH 9 and about pH 13, wherein the presence of the composition in the elution solution provides an increase in nucleic acid recovery, as compared with the recovery in the absence of the composition.
