  • Patent number: 9182391
    Abstract: The present invention provides a measurement reagent that is capable of suppressing nonspecific aggregation even when the amount of antibody to be carried is increased, and is capable of measuring in a wide measurement concentration range with high measurement sensitivity; an immunoturbidimetric assay using the same; and a method of producing thereof. A method of producing an insoluble carrier particle of the present invention is a method of producing an insoluble carrier particle carrying an antibody or an antigen on a particle surface thereof. The method includes a sensitization reaction processes in which the antibody or the antigen is brought into contact with the insoluble carrier particle in the presence of an amino acid with a charged polar side chain in a sensitization reaction solution. The insoluble carrier particles obtained by the producing method of the present invention show favorable dispersibility because nonspecific aggregation is suppressed. As can be seen from Examples 1-1 to 1-4 in FIG.

  • Patent number: 9031091
    Abstract: Operations of a building facility monitoring device and an IP network monitoring device are coordinated with each other. In a connection system of a building facility device managing system, when a status of the IP network monitoring device is changed, a monitoring-device-status managing unit 301 provides parameter information unique for a BACnet protocol to the changed status and stores it. If the status is not an operation command, a coordinated-packet-generation transmitting/receiving unit 302 generates a packet of the BACnet protocol based on a status and parameter information of a specific IP network monitoring device to transmit it to a building facility device managing system 103. If the status is the operation command, it acquires a status and parameter information of the specific IP network monitoring device from a management database 401, and generates a packet of the BACnet protocol based on the status and the parameter information to transmit it to the building facility device managing system 103.
