  • Publication number: 20140141454
    Abstract: An anti-EpCAM monoclonal antibody is provided which specifically recognizes an epitope different from the epitope which conventionally known anti-EpCAM monoclonal antibodies recognize (the N-terminal EGF-like domain). Also provided is a hybridoma which is capable of producing such monoclonal antibody, and a method for detecting CTC using such monoclonal antibody and a kit for detecting CTC, which is used for the method. The present application provides a monoclonal antibody to the human epithelial cell adhesion molecule (EpCAM) as a solution for the above problem, wherein the monoclonal antibody to the human epithelial cell adhesion molecule (EpCAM) specifically reacts with the CP region of the human epithelial cell adhesion molecule (EpCAM) and is produced by a hybridoma with accession No. NITE BP-1449.

  • Publication number: 20120275282
    Abstract: A technique capable of realizing a power saving in a device for reproducing/recording digital signals by controlling a frequency of a clock. The device for reproducing/recording digital signals includes: a difference comparing circuit for comparing a first parameter updated each time a process for one correcting block is done in a demodulating circuit with a second parameter updated each time a process of one correcting block is done in an error correcting circuit; and a circuit for switching a frequency of a master clock depending on a comparison result of the difference comparing circuit. Thereby, the frequency of the clock can be switched both when the demodulation for one correcting block is ended and when the correcting process for one correcting block is ended by using the switched master clock.
