Patent number: 7371849Abstract: The present invention provides camel antibody libraries that maintain in vivo diversity of camelid antibody variable region genes. The in vivo diversity of antibody variable region genes can be accomplished by, for example, mixing genes derived from a plurality of animals or modifying gene amplification conditions. Conventional methods yield only VHHs with limited repertoire diversity. However, the present invention provides libraries comprising genes encoding functional VHHs with sufficient repertoire size. According to the present invention, libraries that enable to freely obtain VHHs against arbitrary antigens are provided. VHHs have excellent solubility and stability, and show a reactivity that usually cannot be expected from tetrameric IgGs.Type: GrantFiled: September 13, 2002Date of Patent: May 13, 2008Assignee: Institute For Antibodies Co., Ltd.Inventors: Toshio Honda, Yasushi Akahori, Yoshikazu Kurosawa

Publication number: 20040259153Abstract: A binding molecule that binds to a binding target substance is selected by introducing an affinity linker into the target binding substance and capturing the substance with a binding partner that binds to the affinity linker. For example, an antibody that binds to an influenza virus antigen can be easily concentrated by labeling a sugar chain present in the antigen with an affinity linker, such as biotin, and then recovering the antigen by binding them to streptavidin. The method for selecting binding molecules of the present invention is also useful in the screening of neutralizing substances.Type: ApplicationFiled: August 4, 2004Publication date: December 23, 2004Inventors: Yoshikazu Kurosawa, Yasushi Akahori, Yukari Hirono, Mai Kakita, Kazuhiro Suzuki, Yoshinobu Okuno
