Abstract:
Provided is a method for detecting an antigen in a sample, the method including: bringing an unlabeled polypeptide and a labeled polypeptide into contact with an antigen in a sample, the unlabeled polypeptide being one of a pair including a VH-region polypeptide and a VL-region polypeptide which are separate and capable of cooperatively recognizing the antigen, and the labeled polypeptide being the other of the pair including the separate VH-region polypeptide and the VL-region polypeptide and being labeled with an environmentally-responsive substance at a site where the environmentally-responsive substance does not inhibit binding of the antigen, and detecting a change in the environmentally-responsive substance caused by a change in the environment around the labeled polypeptide after the contact. Also provided is an antibody fragment polypeptide set including the unlabeled polypeptide and the labeled polypeptide.
Abstract:
A self assembling monolayer formed by the self assembling molecules is caused to bond onto the surface of a base material, and chelators are caused to bond onto the self assembling monolayer, to produce a substrate, in which the chelators are bound to the self assembling monolayer at a density within a range from 0.4/nm2 to 4/nm2. The bonding of the chelators onto the self assembling monolayer being performed within an organic solvent.
Abstract:
A complex, which has been formed by at least two pieces of a ligand and a first metal ion, is bound with a carrier. A second metal ion is then added onto the carrier, a new complex being thereby formed. A substance that contains a Group-15 or Group-16 atom, which has metal coordinating capability, is then fixed to the first metal ion and the second metal ion.
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:
An antibody-fragment-immobilizing substrate includes a substrate and at least one set of antibody fragments, wherein the antibody fragments of each set includes at least two types of separate antibody fragments that are capable of recognizing one type of antigen and that are independently immobilized on the substrate in a positional relationship that allows each of the antibody fragments in one set to bind to the same antigen.
Abstract:
To provide a water purifier, containing: a diluting unit configured to bring targeted water for purification into contact with an aqueous solution containing a volatile solute and a polymer via a semi-permeable membrane so as to separate water from the targeted water by the semi-permeable membrane, and configured to dilute the aqueous solution with the separated water; a separating unit configured to separate the volatile solute and the polymer from the diluted aqueous solution obtained by the diluting unit so as to obtain purified water; and a dissolving unit configured to return the separated volatile solute by the separating unit to the aqueous solution containing the polymer, and to allow the separated volatile solute to dissolve in the aqueous solution containing the polymer.
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.
