A nucleic acid analyzer according to one or more embodiments may include a container setting part that sets a second container, a rotation drive part that rotates the container setting part by applying a driving force to a surface of the container setting part, to supply the extraction liquid injected through the injection port to the storages through the flow path by a centrifugal force. A first temperature adjustment part that adjusts a temperature of the second container provided in the container setting part, such that a nucleic acid amplification reaction occurs in the storages, and a detector that detects a nucleic acid amplification reaction which occurs in the storages with the second container provided in the container setting part interposed between the first temperature adjustment part and the detector in a vertical direction.

Nucleic acid analyzer and nucleic acid analyzing method

A nucleic acid analyzer includes a first container setting part that sets a first container including reagent storages which store reagents for nucleic acid extraction such that the reagent storages are provided along an X-axis extending in a longitudinal direction of the first container; a dispensing unit that transfers, along the-X axis from the first container, extraction liquid containing nucleic acids extracted in the first container using the reagents for nucleic acid extraction; a second container setting part that is provided along the X-axis and sets a second container, the second container including an injection port through which the extraction liquid transferred by the dispensing unit is injected, storages that store reagents for amplifying the nucleic acids in the extraction liquid, and a flow path that connects the injection port and the storages; and a detector that detects a nucleic acid amplification reaction, which occurs in the storages.

A cell processing apparatus includes a storage container that contains liquid L including a biological sample; a filter that prevents a first cell Cin the biological sample from passing and allows a second cell Chaving a smaller diameter than that of the first cell Cto pass; and a filtration cylinder for separating, in the storage container and via the filter, the liquid L into a first liquid Lmainly including the first cell Cand a second liquid Lmainly including the second cell C. A measurement target cell filtered by the filter among other cells can be easily collected.
