  • Publication number: 20200147233
    Abstract: It is an object of the present invention to provide a method for killing tumor cells, having a few side effects. The present invention provides a method for killing tumor cells, comprising: (1) a step of allowing an immunotoxin formed by binding an antibody binding to ROBO1 or a fragment thereof to a cytotoxin to come into contact with tumor cells; (2) a step of allowing a photosensitizer that induces photochemical cytoplasmic internalization to come into contact with the tumor cells; and (3) a step of irradiating the tumor cells with a wave length that is effective for activating the sensitizer, so as to kill the cells.

  • Patent number: 9155805
    Abstract: [Theme] To provide a monoclonal antibody against human GPR87. Also, to provide a novel means for diagnosing or treating a malignant tumor. [Solution means] Monoclonal antibodies against human GPR87 are provided. The antibodies can recognize human GPR87, which is expressed on a cell membrane while retaining a three-dimensional structure, and can recognize GPR87, which is expressed in a cell endogenously with an epitope being present in an extracellular domain of full-length human GPR87. The antibodies are thus useful in biochemical analysis, etc., of GPR87, useful in immunohistological diagnosis, etc., of squamous cell carcinoma, and also potentially useful in PET diagnosis, antibodies for treatment, etc., of squamous cell carcinoma.

  • Publication number: 20100041167
    Abstract: The present invention is directed to a method for diagnosing large intestinal cancer and/or polyp and a method for observing postoperative course or monitoring recurrence thereof, wherein each method includes detecting cystatin SN protein by use of an anti-cystatin SN antibody. The present invention is able to provide a kit for assaying cystatin SN, which can be used, in a simple manner, in a diagnosis performed prior to conventional barium enema examination and endoscopic examination which impose burdens on patients; as an indicator of metastasis and recurrence; and in the evaluation of therapeutic effects. The present invention provides a method for diagnosing or monitoring large intestinal cancer and/or polyp which can be performed in a simple manner, and thus can allow to design a new regimen rapidly.
