Patent number: 9080180Abstract: A technology for producing a pig edema disease vaccine at low cost and at high efficiency is developed. Specifically, a gene of a pig edema disease toxin protein (Stx2e protein) is efficiently expressed in plant cells to produce a plant vaccine for pig edema disease at low cost. An Stx2e protein including a secretory signal peptide derived from a plant added at an amino terminus is expressed in cells of a plant such as Lactuca sativa using the 5?-untranslated region of an alcohol dehydrogenase gene (ADH5?UTR) derived from a plant.Type: GrantFiled: March 25, 2008Date of Patent: July 14, 2015Assignees: IDEMITSU KOSAN CO., LTD., NATIONAL UNIVERSITY CORPORATION NARA INSTITUTE OF SCIENCE AND TECHNOLOGY, NATIONAL UNIVERSITY CORPORATION OBIHIRO UNIVERSITY OF AGRICULTURE AND VETERINARY MEDICINEInventors: Kazutoshi Sawada, Takeshi Matsui, Sou-ichi Makino, Keiko Kawamoto, Mayumi Yoshida, Nobuo Yoshida, Kyoko Yoshida

Patent number: 7343792Abstract: A circuit is used which includes: first and second channels having first and second input ports, respectively, and a third channel having an end where the first and second channel meet and are connected to the third channel. A first liquid to the first input port is supplied to generate a reference flow. A second liquid is supplied by the target pump to the second input port. An interface of the first and the second liquids joined in the third channel is inspected. The operation condition of the target pump is determined from a condition of the inspected interface. Pulsation in the flow supplied by the target pump is detected from waves in the interface visually inspected. The image of the interface may be magnified. Pulsation in the reference pump may be absorbed.Type: GrantFiled: October 19, 2005Date of Patent: March 18, 2008Assignee: FUJIFILM CorporationInventor: Kazutoshi Sawada
