  • Publication number: 20200377833
    Abstract: A cell picking device includes a sucker having a pipette tip attached to a tip portion of the sucker and is used to suck the cell from a tip of the pipette tip, a driver configured to cause the sucker to perform a suction operation and move the sucker in a horizontal-plane direction and an axial direction of the pipette tip with the sucker inclined with respect to a vertical direction. A controller moves the sucker such that the tip of the pipette tip moves in a horizontal direction while being in contact with a bottom surface of the container installed on the sample mounting stage in a predetermined position on the sample mounting stage to desorb a cell arranged in the predetermined position from the bottom surface of the container, and suck the cell desorbed from the bottom surface of the container from the tip of the pipette tip.

  • Publication number: 20200057294
    Abstract: A cell area extraction unit (241) extracts a cell area in a phase image that is created based on a hologram obtained by in-line holographic microscope (IHM). A background value acquisition unit (242) obtains a background value from phase values at a plurality of positions outside the cell area. An intracellular phase value acquisition unit (243) averages a plurality of phase values on a sampling line set at a position close to the periphery of a cell, while avoiding a central portion in which the phase value may be lowered in the cell area, to obtain an intracellular phase value. A phase change amount calculation unit (244) obtains the difference between the intracellular phase value and the background value. A phase change amount determination unit (245) compares the value of the difference with thresholds in two levels to determine whether the cell is in an undifferentiated state or an undifferentiation deviant state.

  • Patent number: 10551386
    Abstract: The present invention provides a biological substance detection method for specifically detecting a biological substance from a pathological specimen, by which method, when immunostaining using a fluorescent label and staining for morphological observation using a staining agent for morphological observation are simultaneously performed, the results of fluorescence observation and immunostaining can be assessed properly even if the fluorescent label and/or the staining agent is/are deteriorated by irradiation with an excitation light. The biological substance detection method according to the present invention is characterized in that the brightness retention rate of an immunostained part is in a range of 80% to 120% in relation to the brightness retention rate of a part stained for morphological observation when the fluorescent label used for the immunostaining is observed.
