Abstract:
A substrate includes: a base material; and chelators which are three dimensionally covalently bound to the base material at a density of 7.8×1015/mm3 or greater and 4.5×1017/mm3 or less, or two dimensionally covalently bound to the base material at a planar density of 2.0×1011/mm2 or greater and 1.0×1013/mm2 or less. Metal ions are coordinately bound to the chelators, and a bioactive substance having histidine tags are coordinately bound to the metal ions. A blocking agent having ligand sets are coordinately bound to the metal ions to which the bioactive substance is not coordinately bound.

Abstract:
A method for purifying bioactive substances includes the steps of: causing a bioactive substance having histidine units to contact media, each constituted by a substrate, ligands which are physically attached to the surface of the substrate, and Cu(II) or Fe(II) metal ions which are covalently bonded to the ligands; causing the bioactive substance to covalently bond with the metal ions via the histidine units; and washing the media with an amount of 1 nmol/L to 10 mmol/L imidazole derivative solution 60 times the volume of the media or greater. In the case that the metal ions are Cu(II), the bioactive substance which has covalently bonded with the Cu(II) via the histidine units are recovered by one of a 10 mmol/L to 1 mol/L imidazole derivative solution and a 0.5 mmol/L to 5 mol/L EDTA solution.
Abstract:
A pinball game is contained within a housing which includes a liquid filled chamber. At least one ball is located within the liquid within the chamber. The ball has a specific gravity heavier than the liquid such that it tends to sink within the liquid but it is light enough to be conveyed upwardly by currents within the liquid. A flipper is located within the chamber and is capable of interacting with the ball to propel it within the confines of the chamber. The flipper is controlled by an actuator member located on the housing and operatively connected to the flipper to move the flipper. At least one goal receptacle is positioned within the chamber and the ball is capable of being located or deposited in the goal receptacle. It is the object to deposit the ball in the goal receptacle by manipulating the ball with the flippers and/or currents of liquid.

Abstract:
A first reactant, which is provided with a reaction site for specific binding with an analyte, and a fluorescent label site, and a second reactant, which is provided with a reaction site for specific binding with the analyte, and a fluorescence recognition site for recognizing fluorescence produced by the fluorescent label site of the first reactant, are respectively fixed onto a support such that the first reactant and the second reactant have a positional relationship adapted for the binding with the analyte.
Abstract:
A toy has a base with a surface thereon. A portion of the surface is movable with respect to the remainder of the surface. A target is mounted on a pedestal above the surface. A self-propelled object is associated with the surface. The object is of the type having a body section and a pedestal section, with a motor located in the body section which is capable of moving the pedestal section with respect to the body section. The object further includes a hand-shaped member which is capable of locking with a post which projects upwardly from the surface of the base near the movable portion of the surface. A moving member is associated with the movable portion of the surface for moving that portion. The moving member is utilized to move the movable portion of the surface such that when the object is located on that portion as the portion moves then the object is also moved.
Abstract:
A toy game of skill has a housing and a plurality of members rotatably mounted on the housing such that they are in operative association with one another. One of the members is rotated, and in so rotating that member, the rotation is communicated to the rest of the members to simultaneously rotate them. Located on the members are a plurality of object repositories. A plurality of objects, at least one less than the number of object repositories, are positioned within the object repositories. As the members move with respect to one another, the objects are carried on the object repositories. The objects can be transferred from one repository to an empty repository when two of the members are in a position aligning their respective object repositories with one another. However, the objects are retained in any one object repository whenever the members are in a position with respect to one another such that the object repositories are not aligned.
Abstract:
A game of the type wherein a transparent housing is filled with a liquid and a movable member is located in the liquid can be made competitive by utilizing a first and second circulating member each capable of ejecting a stream of liquid from a nozzle to move the movable member. The game is improved by incorporating within the interior of a housing two separate pivoting members. Each of the pivoting members is located in association with one of the nozzles and moves in response to impingement of liquid ejected from the nozzles. The ejected liquid impinges upon the surface of the pivoting members to both pivot the members and deflect the stream of liquid. The degree of pivoting and the amount of deflection are dependent on the force of ejection of the stream of liquid. The movable member can be moved within the body of the liquid either by direct contact with one of the pivoting members, by contact with currents in the liquid which are associated with movement of the pivoting members or directed by the ejected streams of liquid.
