<P>PROBLEM TO BE SOLVED: To provide a nucleic acid transfer method which enables an efficient elution and transfer of nucleic acid without destructing a nucleic acid-containing part and requiring much labor, time and technique, a nucleic acid transfer device and a genuineness judgment method of a product. <P>SOLUTION: A nucleic acid-containing printed matter 7 is mounted on a specimen mounting stand and wet filter paper 8 is mounted on the printed matter 7 in a close contact. When electrodes 1 and 1' are brought into contact with the wet filter paper 8, a battery is formed to allow a current to flow and nucleic acid is transferred to the wet filter paper 8 by an electrophoretic theory. The transferred nucleic acid is extracted using a buffer solution to perform PCR amplification and the obtained electrophoretic pattern is compared with the electrophoretic pattern obtained by the transfer from the preliminarily intended place of a true product to judge genuineness. <P>COPYRIGHT: (C)2007,JPO&INPIT |
