Automated nucleic acid processor and automated nucleic acid processing method using multi function dispensing unit

摘要

In relation to an automated nucleic acid processor and an automated nucleic acid processing method using a multi function dispensing unit, processing involving extraction and amplification of the nucleic acid, can be consistently, quickly and efficiently conducted at a low cost with the use of a multi function dispensing unit, while saving user's trouble without expanding the scale of the device. The multi function dispensing unit includes: a nozzle head provided with a suction-discharge mechanism and nozzles detachably provided with dispensing tips; a container group having, at the very least housing parts for liquids and reaction containers for housing an amplification solution; a transfer mechanism that makes an interval between the nozzles and the container group relatively movable; a temperature controller whereby temperature control of the interior of the reaction vessels is possible; sealing liquids and/or sealing lids that are transportable to the reaction vessels using the nozzles, and which make the amplification solutions housed in the reaction vessels sealable within the reaction vessels; and a sealing control part that controls the suction-discharge mechanism or the transfer mechanism, such that the sealing liquid and/or the sealing lids seal the amplification solution within the reaction vessels when the housing of the amplification solution in the reaction vessels is completed.

1. An automated nucleic acid processor using a multi function dispensing unit comprising;
a nozzle head provided with a suction-discharge mechanism that performs the suction and the discharge of gases, and one or two or more nozzles that detachably mount dispensing tips, whereby the suction and discharge of liquids is possible by means of the suction-discharge mechanism; a container group having, at the very least, one or two or more liquid housing parts that house amplification solutions used for nucleic acid amplification and one or two or more reaction vessels; a transfer mechanism that makes an interval between said nozzles and said container group relatively movable; a temperature controller whereby temperature control of the interior of said reaction vessels for nucleic acid amplification is possible; a sealing liquid and/or sealing lids housed in predetermined housing parts other than said reaction vessels of the container group that are transportable to said reaction vessels using said nozzles, which make said amplification solutions housed in the reaction vessels sealable within the reaction vessels; and a sealing control part that controls said suction-discharge mechanism and said transfer mechanism, or said transfer mechanism, such that said sealing liquid and/or the sealing lids seal said amplification solution within the reaction vessels when the housing of said amplification solution in said reaction vessels is completed.
