  • Publication number: 20210402389
    Abstract: A module installation unit is capable of installing a plurality of modules capable of accommodating a plurality of tubes containing a sample. A temperature adjusting unit heats and cools the sample in the tube of each module to the temperature required for nucleic acid amplification. An optical detection unit is used commonly by the plurality of modules installed in the module installation unit and which is capable of detecting the amplified nucleic acid of a sample subjected to nucleic acid amplification of a tube by regulating the temperature via the temperature adjusting unit for each module installed in the module installation unit. A moving unit moves the optical detecting unit and module installation unit relative to each other so as to detect the amplified nucleic acid of the sample in a tube of each of the plurality of modules installed in the module installation unit via the optical detection unit.

  • Patent number: 9523091
    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.
