Provided is a method of purifying nucleic acid, the method including: contacting a nucleic acid-containing sample and a solution containing a kosmotropic salt on a solid support having a hydrophilic functional group on its surface to bind the nucleic acid to the solid support. Since the solid support is used as it is without any surface treatment, manufacture of the apparatus is very easy, and nucleic acid can be bound to the solid support without specific additives in a wide pH range, so that the apparatus can be used for a Lab-On-a-Chip. |
