摘要:
A bacterial toxin protein such as a Shiga toxin protein is efficiently produced using plant cells. The plant cells are transformed using a DNA construct containing DNA encoding a hybrid protein in which the bacterial toxin proteins such as the Shiga toxin proteins are tandemly linked through a peptide having the following characteristics (A) and (B) to produce the bacterial toxin protein in the plant cells: (A) a number of amino acids is 12 to 30; and (B) a content of proline is 20 to 35%.
摘要:
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.

摘要:
A main object of the present invention is to provide a receptor layer forming resin which makes it possible to obtain a receptor layer for a thermal transfer image receptor sheet having excellent dyeing property. The present invention achieves the above object by providing a receptor layer forming polyurethane resin for a thermal transfer image receptor sheet obtained by copolymerizing: a high molecular weight polyol having a number average molecular weight of 1000 or higher (A); an organic isocyanate (B); and according to need, a polyol compound having a number average molecular weight of 500 or lower (C), wherein the receptor layer forming polyurethane resin for a thermal transfer image receptor sheet meets the following requirements (1) to (4): (1) the resin has at least two glass transition temperatures; (2) at least one of the glass transition temperatures is between −200 to 0° C., and at least one is between 20 to 100° C.; (3) the high molecular weight polyol (A) is a mixture comprising; an aromatic polyester polyol containing metallic base sulfonate (A-1); and a polyol other than said (A-1) (A-2); and (4) the ratio of (A-2) in the high molecular weight polyol (A) is 20 mass percent or higher.

摘要:
An electric lock device which can be used suitably regardless of an operation mode of a thumb-turn. In the electric lock device, components to be placed at a peripheral part of the thumb-turn are miniaturized by separating a control device and an electric power supply, which require a comparatively large space, from a thumb-turn cover. The electric lock device includes a cover device internally having a motor and a thumb-turn cover, a control device internally having a control part, and a power supply part built-in the control device for supplying power to the control device and the motor. Therefore, the cover device can be more compactified than that of a conventional electric lock device in which the control part and the power supply part are integrally placed with the thumb-turn cover and the motor. The cover device can be attached proximity to a thumb-turn without being protruded from a door.
摘要:
A method for the stable expression of an introduced exogenous gene in a plant or plant cell is provided. Stable expression of an exogenous gene that was introduced was achieved by operably linking an upstream sequence of sea urchin arylsulfatase gene as an insulator.

To provide a lightweight, rust-free conveyor which is easy to install, remove, and repair. In a plastic conveyor belt, belt element pieces which have connecting holes opening widthwise are joined by communicating the connecting holes lengthwise and are disposed at both widthwise ends. A rod is inserted in a common hole formed at a joint for connection at a lengthwise end, and the respective belt element pieces are rotatably joined around rods to form an endless belt. Rods are installed widthwise between the belt element pieces. A plastic conveyor belt is provided having plastic belt element pieces and rods composed of metallic cores and plastic sheaths, and a conveyor apparatus drives the plastic conveyor belt with a sprocket.
