Patent number: 8815597Abstract: The present invention provides a baglike container for centrifugation that is mounted in a centrifuge to thereby allow centrifugation of a dispersion liquid accommodated therein. The baglike container for centrifugation is less likely to tear or break as a result of centrifugation by disposing a container wall surface of the baglike container so as to apply centrifugal force perpendicular to the container wall surface.Type: GrantFiled: August 23, 2007Date of Patent: August 26, 2014Assignee: Takara Bio Inc.Inventors: Hideto Chono, Junichi Mineno, Kazutoh Takesako, Takao Yoshida, Takashi Morimura, Kenji Sakai, Shin-ichi Yamada, Noritsugu Yabe, Yuko Taguchi

Publication number: 20100247579Abstract: The present invention relates to a method for treatment of cancer, which comprises the following steps (A) and (B): (A) applying a treatment which induces the reduction in lymphocytes to a patient; and (B), subsequent to step (A), administering lymphocytes to the patient promptly. The present invention also relates to a cancer therapeutic agent and a cancer treatment kit for use in the method. When the method is used as an immunoreconstructive therapy, the decrease in immunologic competence which may be caused by the reduction in lymphocytes can be avoided and, therefore, the risk of the occurrence of an infectious disease can be decreased.Type: ApplicationFiled: May 8, 2008Publication date: September 30, 2010Inventors: Hiroshi Shiku, Shinichi Kageyama, Shigehisa Kitano, Mitsuko Ideno, Keisuke Tomita, Tatsuji Enoki, Kazutoh Takesako, Ikunoshin Kato

Publication number: 20100136680Abstract: Baglike container (1) that is fitted in a centrifuge to thereby allow centrifugation of any dispersion liquid placed therein. The baglike container for centrifugation is one comprising a main frame constituted of first container wall (3) with recess portion (6) formed so as to allow fitting in a centrifuge and with flange portion (7) provided on an open face border of the recess portion (6) and constituted of flexible second container wall (4) having its peripheral portion sealed mutually with the flange portion (7) of the first container wall (3) so as to define storing space (6?) for dispersion liquid in cooperation with the recess portion (6) and further comprising port (5) fitted to the main frame in a fashion allowing communication with the storing space (6?), wherein the recess portion (6) defining the storing space (6?) can be set in the centrifuge so that centrifugal force perpendicular to the bottom plane of the recess portion (6) applies.Type: ApplicationFiled: August 23, 2006Publication date: June 3, 2010Inventors: Hideto Chono, Junichi Mineno, Kazutoh Takesako, Takao Yoshida, Takashi Morimura, Kenji Sakai, Shin-ichi Yamada, Noritsugu Yabe, Yuko Taguchi

Patent number: 7491405Abstract: A substantially pure, isolated, antigenic protein from fungi of the genus Malassezia, characterized in that said antigenic protein has a binding ability to IgE antibodies from patients with allergoses; an antigenic fragment derived from the antigenic protein; and an antibody against the antigenic protein or fragments thereof. According to the present invention, there can be provided an isolated and purified antigenic protein having high purity from Malassezia, antigenic fragments thereof, and a specific antibody against those antigenic protein or fragments thereof. In addition, there can be provided a diagnostic agent, a therapeutic agent, or a prophylactic drug for Malassezia allergoses, wherein the agent includes, as an active ingredient, the antigenic protein or fragments thereof.Type: GrantFiled: April 28, 2005Date of Patent: February 17, 2009Assignee: Takara Bio Inc.Inventors: Kazutoh Takesako, Takashi Okada, Tomoko Yagihara, Masanobu Kuroda, Yoshimi Onishi, Ikunoshin Kato, Kazuo Akiyama, Hiroshi Yasueda, Hideyo Yamaguchi

Patent number: 7485448Abstract: A method for obtaining a virus vector free of a serum, and a serum-free medium for cultivation of a virus producer cell which can be used for the method are provided. By cultivating a virus producer cell using a serum-free medium containing serum albumin, it is possible to cultivate the cell in a state equivalent to that in a serum-containing medium to produce a virus vector at a sufficient titer. The virus vector prepared from the virus producer cell cultivated in the medium exhibits gene transfer efficiency comparable to that of a conventional vector. The medium is useful for gene therapy and studies thereof.Type: GrantFiled: September 13, 2006Date of Patent: February 3, 2009Assignee: Takara Bio Inc.Inventors: Hirofumi Yoshioka, Yasushi Katayama, Daisuke Tomura, Masao Funakoshi, Kazuya Matsumoto, Junichi Mineno, Kazutoh Takesako, Ikunoshin Kato
