  • Publication number: 20090246805
    Abstract: A method for counting basophils which comprises: (1) mixing and reacting a blood sample with an anti-CD123 antibody labeled with a first fluorescent label and an anti-CD294 antibody labeled with a second fluorescent label to prepare a measurement sample, (2) introducing the measurement sample into a flow cell of a flow cytometer and irradiating, with light, cells in the measurement sample flowing in the flow cell, (3) detecting fluorescences from the first and second fluorescent labels as well as two scattered lights different in angle, emitted from the cells, (4) identifying basophils on the basis of the detected fluorescences from the first and second fluorescent labels as well as the two scattered lights different in angle, and (5) counting the identified basophils. A kit for measuring basophils which comprises a CD123 antibody labeled with a first fluorescent label and a CD294 antibody labeled with a second fluorescent label.

  • Patent number: 6893294
    Abstract: A transceiver cage to accommodate a transceiver module. The transceiver cage includes a housing having a top plate, a bottom plate, a back plate, a first side plate, and a second side plate. There is an opening at a front of the housing for the insertion of the transceiver module. The transceiver cage further includes at least one resilience piece protruding from an inner wall of the housing toward the front and a latch holding the transceiver module accommodated in the housing against a force of the resilience piece. The transceiver module is detachably accommodated in the transceiver cage by locking and releasing the latch. The resilience piece includes a first bend section having a proximal end for joining the housing and the resilience piece, a second bend section having a protruding end, and at least one intermediate bend section provided between the first bend section and the second bend section.

  • Publication number: 20040247318
    Abstract: Nodes (4A, 4B, 4C, 4D) take optical signals different in wavelength from one another out of a network optical fiber (3), and send out optical signals different in wavelength from one another to the network optical fiber (3). A controller (5) converts an optical signal received through the network optical fiber (3) into an optical signal of the wavelength assigned to the destination node, based on address information contained in the received optical signal, and outputs the optical signal after the conversion to the network optical fiber (3).
