Abstract: A USB test device and method for testing a power reception device having a USB plug, the USB test device including a connector connected to the USB plug, a communication control unit that communicates with the power reception device through a communication line of the connector, a power supply control unit capable of supplying electric power to the power reception device through a power supply line of the connector, a test control unit that gives an instruction to the power supply control unit based on a power request from the power reception device obtained by the communication control unit, and examines a state of power supply to the power reception device, and a display unit that displays a result of examination by the test control unit.

Abstract: A USB test device for testing a power feed device having a USB plug includes: a connector connected to the USB plug; a communication control unit that communicates with the power feed device through a communication line of the connector; a load control unit capable of controlling a load of a power supply line of the connector receiving power supply from the power feed device; a test control unit that gives an instruction to the load control unit based on power supply information which was obtained by the communication control unit and which is about a combination of electric power that can be supplied from the power feed device, and examines a state of power supply to the load from the power feed device; and a display unit that displays a result of examination by the test control unit.

Abstract: The present invention relates to a fluorescent probe for flow cytometry that includes a carrier molecule and porphyrin bound to the carrier molecule and in which an excitation wavelength of the fluorescent probe for flow cytometry is in a range of 350 to 650 nm. The present invention also relates to a method for screening fluorescence-labeled cells using a flow cytometer that includes a step of fluorescently labeling cells with a fluorescent probe for flow cytometry and a step of screening fluorescence-labeled cells labeled with the fluorescent probe for flow cytometry using a flow cytometer, and in which the screening of the fluorescence-labeled cells using a flow cytometer is performed by irradiating the fluorescence-labeled cells with excitation light with a wavelength of 350 to 650 nm and detecting fluorescence.

Abstract: The present invention relates to a fluorescent probe including a carrier molecule, a fluorescent dye a bound to the carrier molecule, and a fluorescent dye b bound to the carrier molecule in which the excitation wavelengths of the fluorescent dyes a and b are different, and FRET does not occur between the fluorescent dyes a and b. The present invention also relates to a method for detecting fluorescence that includes a step of labeling target cells with the fluorescent probe, and a step of irradiating the target cells labeled with the fluorescent probe with excitation light and observing the fluorescence from the fluorescent probe.
