    摘要: The present invention relates to materials for extracting nucleic acid using charge switch methods which involve, at a first pH, bringing the sample into contact with a material which comprises an ionisable group, wherein the material has a positive charge at said first pH, such that nucleic acid is bound to the material; and releasing the nucleic acid at a second, higher, pH at which the charge on the material is negative, neutral or less positive. The release of the nucleic acid occurs under mild conditions and the ionisable group is provided by a biological buffer, a polyhydroxylated amine, a detergent or surfactant, a carbohydrate, a nucleic acid base, a heterocyclic nitrogen-containing compound, a monoamine, a biological dye, or a negatively ionisable group, the pKa of which is between about 3.0 and 7.0 and a metal oxide which is positively charged at said first pH, and optionally also at said second pH.
