Nucleic-acid extraction method and nucleic-acid extraction cartridge
First Claim
1. A nucleic-acid extraction method, the method comprising:
- inserting a sample containing a nucleic-acid into a negative-electrode side area between a dialysis membrane and a negative electrode;
performing an ultrasonic process on the sample containing a nucleic-acid and adjusting the time and frequency of the ultrasonic process based on the type of the sample;
adsorbing foreign substances contained in the sample using an adsorption carrier after performing the ultrasonic process; and
blocking an electrophoresis movement of the nucleic acid to condense the nucleic-acid on a boundary face of the dialysis membrane after adsorbing the foreign substances, whereinbead particles are inserted into the negative-electrode side area before the sample containing the nucleic-acid is inserted into the negative-electrode side area.

Abstract
The present disclosure provides a nucleic-acid extraction method for carrying out the following procedures in the same cell, the procedures including: performing an ultrasonic process on a sample containing a nucleic acid; adsorbing substances contained in the sample by making use of an adsorption carrier; and condensing the nucleic acid by damming the nucleic acid moving in an electrophoresis phenomenon. In accordance with the nucleic-acid extraction method, it is possible to carry out an ultrasonic process, an adsorption process and an electrophoresis process in the same cell. Thus, it is possible to eliminate an operation to transfer the sample from one cell to another one for each of the processes.
