Patent number: 8883977Abstract: 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.Type: GrantFiled: April 28, 2011Date of Patent: November 11, 2014Assignees: Shionogi & Co., Ltd., National University Corporation Hokkaido UniversityInventors: Shin-Ichiro Nishimura, Shoichi Naito, Naoki Ohyabu, Tatsuya Takahashi, Yoshito Numata, Keiko Kawamoto

Patent number: 8722856Abstract: 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.Type: GrantFiled: October 28, 2009Date of Patent: May 13, 2014Assignees: National University Corporation Hokkaido University, Shionogi & Co., Ltd.Inventors: Shin-Ichiro Nishimura, Hiroshi Hinou, Yoshito Numata, Junji Onoda, Shoichi Naito, Naoki Ohyabu
