Definitions
- the present invention relates to a genetic analysis apparatus using a reaction vessel suitable for conducting a rapid genetic analysis research or clinical practice in basic life science, medical basic research and medical practice, for example, animals such as humans.
- the present invention relates to gene analysis that handles a reaction apparatus for detecting a specific base sequence at high speed from nucleic acid base sequences such as genomic DNA of plants and messenger RNA.
- PCR Polymerase chain reaction
- Thermal cycling is performed by raising and lowering the temperature of the reaction vessel used for the DNA amplification reaction.

- the temperature speed of the heater or Peltier element is as low as several degrees C per second, and it is difficult to change the temperature without over-surreal temperature. Basically, if heat conduction in a solid is used, a thermal gradient is formed between the heat source and the surface, and strict control is impossible. Further, heat is taken away at the moment when the sample touches the heater or Peltier element, and a delay occurs until the surface temperature returns to the predetermined temperature. When the reaction tank is brought into contact with a different heater or liquid bath, the movement mechanism is complicated, or the temperature control of the heater or liquid bath is difficult. Furthermore, in the method of flowing a sample through channels having different temperature regions, there is a problem that the surface temperature of the channel itself changes as the sample moves, making temperature control difficult. In addition, when changing the temperature by blowing warm air, it is necessary to blow a large amount of air because the heat capacity of air is small. It is difficult to strictly control the typical blowing temperature in units of 1 ° C.
