  • Patent number: 10544453
    Abstract: There is provided an apparatus for detecting a nucleic acid amplification product in real time, which is capable of effectively excluding or reducing apparatus error factors without using a second fluorescence signal used for correction. A plurality of wells 7A are given with temperature cycles and fluorescence strength from a nucleic acid amplification product is detected in real time in each well 7A. A fluorescence measurement value [DNA]raw obtained from the well 7A and a fluorescence measurement value [DNA]bg obtained from a connection wall near the well 7A are detected, and the fluorescence measurement value [DNA]bg is subtracted from the fluorescence measurement value [DNA]raw to determine fluorescence strength [DNA]real of the well 7A.

  • Patent number: 9511363
    Abstract: An isolator includes a work chamber, a sterilizing substance supply unit, a gas flow channel pressure adjustment unit, a work chamber barometer, and a controller. The controller is configured to control execution of a gas flow channel leak test for checking a gas leak in a gas flow channel based on a detection result by the work chamber barometer after making the gas flow channel pressure adjustment unit increase or decrease the pressure in the gas flow channel, and is configured to control supply of the sterilizing substance by the sterilizing substance supply unit. The controller performs heating of a heater, which accompanies the supply of the sterilizing substance, in parallel with the gas flow channel leak test.
