Abstract:
1. A nucleic acid detecting cassette for detecting nucleic acid contained in a sample, comprising: a stationary member; a flexible member provided on the stationary member, the stationary member and flexible member forming a fluid holding channel, a joining channel and an inlet-outlet port therebetween, the fluid holding channel being configured to be able to vary its inner volume, and hold a reagent, the fluid holding channel having a channel starting edge portion and a channel terminating edge portion, the inlet-outlet port being connected to the fluid holding channel and being selectively set to one of an open-state under which the fluid holding channel is communicated with the outside of the cassette through the port and a closed-state under which the fluid holding channel is discommunicated with the outside of the cassette, the joining channel being connected to the fluid holding channel, and being provided to at least one of the channel starting edge portion and the channel terminating edge portion of the fluid holding channel, the joining channel being selectively set to one of an open state under which the communication with the fluid holding channel is made and a closed-state under which the communication with the fluid holding channel is interrupted; a first opening-closing part configured to maintain the inlet-outlet port under the closed-state; and a second opening-closing part configured to maintain the joining channel under the closed-state.
