Patent application numberDescriptionPublished
20080233634NUCLEIC ACID DETECTION DEVICE - A nucleic acid detection device is provided with a closed channel formed of a first channel portion, through which a washing reagent storage section for storing a washing reagent for washing a detection section for nucleic acid detection communicates with the detection section, and a second channel portion through which a pretreatment section for nucleic acid treatment communicates with the detection section. The closed channel is connected with a gas inlet/outlet path for communication with the outside. The gas inlet/outlet path is blocked by a sealing mechanism before nucleic acid detection. In storing a pretreatment reagent and the washing reagent frozen, the gas inlet/outlet path is kept open and connected to the channel. Thus, there is provided a nucleic acid detection device having a structure for preventing leakage of nucleic acid samples to the outside and which can be stored for a long period of time with the reagents therein.09-25-2008
