摘要:
A hybridoma obtainable by fusing a spleen cell or lymphocyte of an animal immunized by a complex of a surfactant compound for synthetic detergent and protein with a myeloma cell, which produces a monoclonal antibody against the compound or its degradation product. A monoclonal antibody against a surfactant compound for synthetic detergent or its degradation product which is produced by the hybridoma, a kit for immunoassay of detergent, its degradation product or a mixture thereof containing as an essential constitutional component the monoclonal antibody, and an immunoassay method, in particular, ELISA of detergent, its degradation product or a mixture thereof in a specimen by reacting the specimen with the monoclonal antibody supported on a carrier and the detergent, its degradation product or the mixture thereof labeled with a labeling agent are also disclosed.

The present invention provides a protein capable of binding to an environmental hormone, which protein is supplemented with useful properties for measuring, quantifying and concentrating environmental hormones, such as high sensitivity, low cross-reactivity, unlikelihood of being influenced by interfering substances, and unlikelihood of being influenced by solvents. Specifically, the present invention provides a modified protein prepared by obtaining various genes for various antibodies with environmental hormones, and modifying, by gene recombination technology, various properties of the original antibody, such as affinity, avidity, cross-reactivity, resistance for interfering substance on antigen-antibody reaction, resistance for interfering substance on enzymatic color developing reaction, resistance for solvent and the like.

A seismic isolation device comprises a floor body which is arranged on a structural floor and to which an object of seismic isolation is mounted, a first restoring member disposed on the structural floor and adapted to impart a horizontal restoring force to the floor body when the floor body is horizontally displaced with respect to the structural floor, a first damping member arranged in association with the first restoring member and adapted to impart a horizontal damping force when the floor body is horizontally displaced with respect to the structural floor, a first engaging member projecting from the floor body towards the structural floor, a second engaging member provided on the first restoring member and sliding while coming into contact with the first engaging member, a second restoring member disposed to a lower portion of the floor body and adapted to impart a vertical restoring force when the floor body is vertically displaced with respect to the structural floor, a second damping member arranged in association with the second restoring member and adapted to impart a vertical damping force when the floor body is vertically displaced with respect to the structural floor, and a support mechanism for supporting the floor body to be movable in a horizontal direction.
摘要:
An apparatus for repairing a liquid crystal display comprises a common electrode, pixel electrodes facing the common electrode, and a liquid crystal sealed between the common and pixel electrodes. If the liquid crystal contains foreign matter which short-circuits the common and pixel electrodes to each other, a pixel electrode is irradiated with a laser beam such that at least a ring line region completely surrounding a portion touching the foreign matter is burnt away, whereby a region inside of the ring line region and a region outside of the ring line region are electrically insulated from each other.

A method for producing high yields of interferons which comprises cultivating a microorganism carrying an expression vector with a structural gene of interferon inserted therein in a chemically defined medium containing L-glutamic acid and an iron ion source and preferably further containing an zinc ion source or zinc and copper ion sources, and recovering interferon from the culture.
摘要:
A welding head which can easily move the torch portion of the welding head in the circumferential direction and the vertical moving direction of the outer circumference of the to-be-welded tubes even in a narrow gap, includes a torch rotating ring that rotates on the outer circumferences of the tubes by matching with the central axis of the to-be-welded tubes and a torch vertical moving ring disposed concentrically with the ring inside the ring, provided with a torch base for supporting a torch on the front ends, a first gear group for driving and rotating the ring around the tubes, a second gear group that is disposed in parallel to the first gear group and drives and rotates the ring around the tubes, a drive shaft for driving the two gear groups, and a torch rotating motor for driving the drive shaft, and a third gear group that can drive the ring while rotating it in the same direction as or in reverse to that of the ring at a speed equal to or higher or lower than that of the first gear group for rotating the ring around the tubes and vertically moving the torch, and a torch vertical moving motor for driving this third gear group.
摘要:
The present invention provides a method of producing an antibody-producing hybridoma, which includes fusing a B cell immunized in vitro and a myeloma cell, and which is more efficient and practical than the conventional methods, more specifically a method of producing an antibody-producing hybridoma, which includes fusing a B cell immunized with an antigenic substance in the coexistence of a cytokine and a glycolipid in vitro, and a myeloma cell, and use thereof.
摘要:
A seismic isolator has a sliding plate fixed on the lower surface of a building, a connecting plate underlying the sliding plate, an elastic first support disposed between the connecting plate and a foundation of the building to support the building, a second support disposed between the connecting plate and the foundation and urged by a biasing force of a spring member such that its upper end is brought into tight contact with the lower surface of the connecting plate, and a jack for adjusting the biasing force of the spring member. A frictional force acting between the sliding plate and the connecting plate is larger than that between the connecting plate and the upper end of the second support.
摘要:
A floor system includes a plurality of panels placed on a base floor. A space is formed between the panels and the base floor for laying cables. A plurality of sliding plates are arranged on the base floor. A plurality of supports are provided and each support of the plurality of supports is arranged on each of the sliding plates so as to freely slide. The plurality of panels are supported by the plurality of supports by being fixed on a pedestal of the each support of the plurality of supports. The plurality of panels are hence connected to each other to form a single floor surface. The dynamic coefficient of friction between the bottom of the supports and the sliding plates is selected to be a value within a range of 0.09 to 0.25.
