  • Patent number: 8883977
    Abstract: An objective of the present invention is to provide a MUC1 antibody having high specificity to cancer cells. The objective has been achieved by the present inventors who found that a cancer-specific sugar chain can be specifically recognized in MUC1 and a cancer cell expressing MUC1 having such a cancer cell specific sugar chain can be recognized. The present invention provides an antibody, an antigen-binding fragment thereof or a MUC1-binding molecule, having, for example, 40-fold specificity or more for a cancer-associated structure of MUC1 as compared to that of a normal tissue-associated structure of MUC1.

  • Patent number: 8722856
    Abstract: An object of the present invention is to provide an antibody which does not bind to a normal cell, and is specific for a cancer cell. The object was solved by the finding by the present inventors that an antibody obtained by immunizing an animal using a 2,3ST glycopeptide as an antigen unexpectedly recognizes a sugar chain specific for a cancer specifically and remarkably, and consequently, can recognize and kill a cancer cell expressing MUC1 having such a cancer cell-specific sugar chain. The present invention provides, for example, an antibody, an antigen-binding fragment thereof or a MUC1-binding molecule, in which specificity for a cancer-associated structure of MUC1 is 100-fold or more as compared with that for a normal tissue-associated structure of MUC1.

  • Patent number: 8536313
    Abstract: A neutralizing monoclonal antibody specifically reacting with MMP13, a method of neutralizing enzyme activity of MMP13 and an immunological measuring method each using the antibody, as well as a diagnostic agent and a pharmaceutical composition containing the antibody, are provided. Various antibodies to MMP13 have been hitherto obtained, but an antibody having neutralizing activity against MMP13 has not been obtained. The present inventors intensively studied, as a result, found out a neutralizing antibody having specificity for MMP13, resulting in completion of the present invention.
