摘要:
The improved DNA base sequencer comprising an electrophoresis plate having a gel electrolyte layer held between two glass plates, one of which is partially cut away on the top edge in the direction of width, an assay compartment for accommodating said electrophoresis plate in a vertically erect position, a lower reservoir of a buffer solution in which the lower part of the gel electrolyte layer in the electrophoresis plate is to be immersed, an upper reservoir of a buffer solution in which the upper part of said electrolyte layer is to be immersed, photoexciting laser light applying means by which laser light is emitted from a lateral side of the electrophoresis plate in such a way that it crosses the lanes in said plate at right angles, and fluorescence detecting means by which the fluorescence emitted from a DNA fragment illuminated with the laser light is picked up and converted to an electric signal, and the apparatus is characterized in that a sharkstoothcomb made of a water-swellable material is inserted from the top edge of said electrophoresis plate into the space between the two glass plates, either the top or bottom edge of said sharkstoothcomb being provided with a plurality of teeth which are each tapered from the root toward the tip. Using this apparatus, samples can be easily and yet positively injected at specified lane positions on the gel electrolyte layer.

A test reagent container includes: a bottom part; a peripheral wall part on the periphery of the bottom part; a storage part which opens upward and with an internal diameter of an inner peripheral wall decreased with depth; a film which seals the opening of the storage part; a discharge channel which penetratingly passes from an inner bottom surface of the storage part to the bottom part of the container body; a projecting part formed downwardly projecting from the bottom part to seal an outlet of the discharge channel; a breakable part including a thick-walled part and a thin-walled part thinner than the thick-walled part formed on the periphery of the projecting part. The breakable part is broken when the projecting part is depressed from outside of the container, the projecting part is inserted into the inside of the discharge channel, and the sealed state of the outlet is released.

A test reagent container including a discharge port, formed by depressing a projecting part formed on a container bottom part, through which content can be easily and reliably discharged. The test reagent container includes: a bottom part; a peripheral wall raised approximately perpendicularly from a periphery of the bottom part; and a storage part defined by the bottom part and peripheral wall. A projecting part is formed on the bottom part in a projecting manner toward outside the container. A proximal end of the projecting part is formed in a bendable manner relative to the bottom part, and an easily breakable part is formed on a periphery of the projecting part except for the proximal end of the projecting part. The easily breakable part is broken when the projecting part is depressed from outside the container to be pushed into the inside of the container to form a discharge port.

The micro-channel chip for electrophoresis of the present invention comprises a first substrate formed of a gas-permeable material and a second substrate formed of a gas-permeable or a gas-impermeable material, the first and the second substrate being glued together, the mating surface of either one of the first and second substrates having a sample-feeding channel having a port at both ends and an electrophoretic channel also having a port at both ends, the sample-feeding channel and the electrophoretic channel being allowed to communicate with each other via a narrower channel having a smaller cross-sectional area than those two channels. The micro-channel chip for electrophoresis of the present invention requires only one power source to perform electrophoresis and can use samples with minimum waste of their quantity.

A game is provided based on real data which changes with time reflecting phenomena occurring in real life. In a game system 10 for providing a virtual stock trade game to players base on the real life stock price data, stock price data is obtained in almost real time from a broker etc., and stock virtually owned by the player in a game space corresponding to real life is evaluated by the stock price data. By allowing the players to compete for a time period until a target total asset value is achieved, a new player can compete under almost the same circumstances as the preceding players regardless of the timing at which they started participating in the game.

The improved DNA base sequencer comprises a flat plate type gel electrophoretic means that has a multiple of tracks for electrophoresing DNA fragments and which is held in a vertical position, a light exciting laser light applying means that applies laser light to the respective tracks in said electrophoretic means from one lateral side thereof in such a way that it crosses said tracks at right angles, and a fluorescence detecting means that detects the fluorescence as generated from the DNA fragments illuminated with the laser light and which converts the detected fluorescence to an electric signal, and it is characterized in that the fluorescence detecting means comprises an index-distributed lens array, a filter and a solid-state imaging device such as a CCD line sensor. This apparatus uses light-receiving optics that does not include a large and expensive optical device such as an image intensifier and which yet is capable of efficient fluorescence detection without "smiling" and other adverse effects.

A game system (1) executes a sport video game that uses a moving object (52), and stores evaluation standard data which associates an area (76) in a game space (30) with an evaluation standard for evaluating the result of movement of the moving object (52) from a point inside the area (76). A moving control unit (98) moves the moving object (52) from a moving start point based on the result of detection by a game operation detecting unit (96). A determining unit (100) determines whether or not the result of the movement of the moving object (52) from the moving start point satisfies an evaluation standard that is associated with the area (76) that contains the moving start point. A game operation evaluating unit (102) evaluates a game operation performed by a player based on the result of determination of the determining unit (100).

There is provided by the present invention a novel micro passage chip having such a structure that a fluid can be transferred without using a physical or mechanical squeezing means that is applied from above the substrate of the micro passage chip. The micro passage chip of the present invention comprises at least a first substrate, a second substrate, and an intermediate substrate interposed between the first substrate and the second substrate and is characterized in that a first non-adhesive thin-film layer is formed on at least one of the mating sides of the first substrate and the intermediate substrate and at least one port for fluids that is in contact with the first non-adhesive thin-film layer and which is open to the outer surface of the first substrate is provided in any position on the first non-adhesive thin-film layer, and that at least a portion of a second non-adhesive thin-film layer whose length is either the same as or different from that of the first non-adhesive thin-film layer is formed on at least one of the mating sides of the second substrate and the intermediate substrate such that it lies either above or under the first non-adhesive thin-film layer, with the intermediate substrate lying in between, and a pressurizing port that is in contact with the second non-adhesive thin-film layer and which is open to the outer surface of the first or the second substrate is provided in at least one area on the second non-adhesive thin-film layer.
