  • Method for producing antibody directed against protein expressed on cell surface
    Patent number: 9090672
    Abstract: Disclosed is a method for producing an antibody directed against a protein, particularly a transmembrane protein, expressed on the surfaces of cells. Specifically disclosed is a means for obtaining a desired antibody by mixing cells capable of expressing an antigen protein on the surfaces thereof (i.e., antigen molecule-expressing cells) with an antibody library composed of antibody-expressing cells, viruses or the like, and subsequently concentrating/isolating only components (e.g., antibody-expressing cells, viruses) capable of binding to the antigen molecule-expressing cells from the components (e.g., antibody-expressing cells, viruses) of the antibody library.
    Type: Grant
    Filed: December 7, 2009
    Date of Patent: July 28, 2015
    Assignee: CHIOME BIOSCIENCE INC.
    Inventors: Shu-ichi Hashimoto, Donghui Li, Shoko Ishida, Hidetaka Seo, Chika Koyama, Yukiko Banzai, Naoto Harigai, Isao Kohno
