In particular, aqueous compositions for stabilizing DNA contained in biological samples at ambient temperature are disclosed, together with associated methods and kits using same. In one aspect, the compositions comprise a chelating agent present at a concentration of at least about 150 mM, and the composition has a pH of at least about 9.5.
