摘要:
The plasmid of the present invention contains Leu 2 gene (.beta.-isopropylmaleate dehydrogenase gene) from Saccharomycopsis lipolytica and an autonomously replicating sequence (hereafter referred to as ARS) and can be a shuttle vector between Escherichia coli and Saccharomycopsis lipolytica since it is produced from shuttle vector pVC 1 of Escherichia coli and Saccharomyces cerevisiae. An exogenous useful gene is inserted into the plasmid of the present invention, namely, shuttle vector to transform Escherichia coli, whereby a large quantity of plasmids are obtained. It becomes possible to produce a useful substance in Saccharomycopsis lipolytica as a host using the plasmid.

An image recording apparatus which effects digital exposure while aiming for compactness. An exposure unit digitally exposes a photosensitive material successively while moving above a stage. An application unit moves from the rear side of the exposure unit and applies water successively to the photosensitive material. A superposing unit moves from the rear side of the application unit, and successively superposes an image-receiving material on the photosensitive material. Heat development transfer is carried out, and an image is obtained on the image-receiving material.

An image recording apparatus, in which a necessary place can be suitably exposed by simple operation and the workability of inspection, maintenance and the like improves, is obtained. In the image recording apparatus, an upper cover is rotatably connected to and supported at a base stand by an intermediate hinge. Accordingly, there are a first stage opened/closed state, in which the upper cover opens and closes around a supporting shaft, and a second stage opened/closed state, in which the upper cover integrally opens and closes along with the intermediate hinge around another supporting shaft. In the second stage opened state, the inner portion of the base stand is exposed by a large amount, the distal end portion of a stage is lifted, and further, the holding of a supply magazine and a take-up magazine is released. As a result, the innermost place within the apparatus is exposed and the workability of inspection and maintenance, such as replacement of the supply magazine or the take-up magazine, improves.

The present invention provides a gene encoding the type B subunit protein of avian lactate dehydrogenase. The gene encoding the type B subunit protein of avian lactate dehydrogenase of the present invention is obtained by plaque hybridization or the like from a cDNA library derived from avian heart muscle and encodes the type B subunit protein of avian lactate dehydrogenase having the sequences shown as SEQ ID NO. 1 or 2.
摘要:
The present invention provides a method for producing nested deletions in vitro in desired DNA, comprising: 1) preparing a vector containing a DNA fragment in which nested deletions are to be generated and the terminal repeat of a transposon; 2) incubating the vector in vitro with transposase and a DNA replication system; 3) obtaining the vector incorporating the DNA fragment with nested deletions as a reaction product; and optionally, 4) transforming a host cell with the reaction product and growing it; and 5) recovering a vector incorporating said DNA fragment with nested deletions from the grown host cell.
摘要:
A sample is treated with a phosphoglyceric acid mutase (PGAM) inhibitor (polythionic acid (salt) such as potassium tetrathionate) to inactivate the M-type isozyme activity and the B-type PGAM is quantified by determining PGAM isozymes by a rate assay. The B-type PGAM is a novel marker for cerebral apoplexy, and the diagnosis of cerebral apoplexy is enabled by assaying it.
摘要:
The vacuum deposition device includes a vacuum deposition chamber, a vacuum evacuator for evacuating an inside of the chamber, an evaporating unit for evaporating one or more film forming materials in the chamber, a holding unit provided above the evaporating unit for holding a substrate for the vacuum deposition, and a preventing unit for preventing evaporated particles of the one or more materials from adhering to the substrate when the vacuum deposition is carried out at a pressure of 0.05 to 10 Pa. The pretreatment method for the vacuum deposition prepares the prevention unit in the chamber and melts the one or more materials by heating in the chamber at the pressure of 0.05 to 10 Pa while preventing the evaporated particles from adhering to the substrate by using the preventing unit.

摘要:
A sheet material supplying apparatus having a low-cost sucker adsorbing unit of a simple structure is provided for the carrying of sheet materials that are used under a high-humidity environment or that include humidity, to ensure a proper separation of each sheet material. Sheet materials accommodated in a tray are being sandwiched between a push-up panel and an engagement claw. At the time of taking out the sheet materials from the tray, the push-up panel is pressed down by a cam to cancel the state of sandwiching between the engagement claw and the push-up panel. Accordingly, only the top layer sheet material is taken out from the tray, with the rest of the lower layer sheet materials being dropped by their self-weight. Further, the sheet materials are carried by the sucker adsorbing unit. When a sucker adsorbing a sheet material by a negative pressure has moved to a carrying roller, a sucker supporting section is elastically deformed by a sucker pressing unit, so that the negative pressure within the sucker can be cancelled. Accordingly, a complex control system is not required for cancelling the negative pressure.
