  • Highly effective anti-cadherin antibody for induction of antibody-dependent cellular cytotoxicity in vivo
    Patent number: 9017683
    Abstract: It is an object of the present invention to provide an anti-cadherin antibody having high antibody-dependent cellular cytotoxicity. The present invention provides an anti-cadherin antibody, which recognizes any one of an upstream region of EC1, a cadherin domain 4 (EC4) and a cadherin domain 5 (EC5), wherein an antibody-dependent cellular cytotoxicity at an antibody concentration of 1 ?g/mL is 30% or more.
    Type: Grant
    Filed: May 3, 2013
    Date of Patent: April 28, 2015
    Assignees: The University of Tokyo, Perseus Proteomics Inc.
    Inventors: Hiroyuki Aburatani, Lilin Zhang, Keisuke Ishii, Katsushi Kouda, Aya Sakamoto, Keiko Katsumi, Hiroshi Onishi, Yoko Kayukawa
