摘要:
A method for simply measuring a 1,2-dicarbonyl derivative in multiple specimens is provided, which comprises converting a 1,2-dicarbonyl derivative to a pyrazine derivative represented by the formula (I): wherein R1 and R2 independently represent a hydrogen atom, a methyl group, a hydroxymethyl group, a hydroxyethyl group, a dihydroxyethyl group, a dihydroxypropyl group, a trihydroxypropyl group, or a trihydroxybutyl group, A represents a group that binds to the pyrazine ring to form a 6-membered aromatic hydrocarbon group, a 5- or 6-membered aromatic heterocyclic group, or a 5- or 6-membered alicyclic hydrocarbon group, and R3 represents a linking residue, wherein said 5-membered ring formed by A may have 1 or 2 substituents and said 6-membered ring may have 1 to 3 substituents, in addition to R3 and measuring the pyrazine derivative by an immunological method using an antibody that recognizes the pyrazine derivative.
摘要:
A phenytoin derivative represented by formula (I) ##STR1## wherein Ph denotes a phenyl group,X denotes --O--, --NH-- or --CH.sub.2 --,Y denotes --CO-- or --CH.sub.2 --,Z denotes a hydrogen atom or a hydroxyl group,M denotes a salt-forming cation, andm and n are each an integer of 0 to 8 and m+n is at least 2.Said compound is useful to produce a phenytoin-labelled DNA or RNA probe. When using such a probe, DNA or RNA in the specimen can be detected with high sensitivity.

A method for measuring glycated hemoglobin is disclosed, which comprises contacting a sample with an anti-hemoglobin antibody being bound to a solid phase, adding thereto an anti-glycated hemoglobin antibody, and then measuring the anti-glycated hemoglobin antibody bound to the solid phase via glycated hemoglobin and the anti-hemoglobin antibody. A method for measuring glycated hemoglobin is further disclosed, which comprises mixing a sample with particles on which an anti-glycated hemoglobin antibody is bound to cause immunoagglutination reaction. A method for measuring glycated hemoglobin is furthermore disclosed, which comprises mixing a sample with a solution containing a monoclonal antibody specific for glycated hemoglobin, and then measuring the change in the turbidity of the resulting mixture. A method is disclosed for measuring glycated hemoglobin which comprises mixing a sample with unsensitized latex particles and an anti-glycated hemoglobin antibody, to cause immunoagglutination reaction. There is disclosed a method for measuring glycated hemoglobin which comprises mixing a sample with unsensitized latex particles and particles on which an anti-glycated hemoglobin antibody is bound, to cause immunoagglutination reaction. Still furthermore, an anti-glycated hemoglobin monoclonal antibody having a high specificity for human glycated hemoglobin is disclosed.
摘要:
In order to provide a constituting part for a fuel battery in which a number of steps of assembling the constituting parts for the fuel battery can be reduced, and in which the replacing property and the maintenance property of fuel battery cell parts can be improved and the cost for parts can be reduced, the structure is made such that a separator made of a carbon plate or substantially similar material, a gas diffusion layer made of a carbon fiber or substantially similar material, and a gasket made of a liquid rubber cured material or substantially similar material are integrally formed, and further, gaskets are respectively provided on both surfaces of a pair of gas diffusion layers holding an independent electrolyte membrane from both sides thereof between the pair.
摘要:
In order to provide a gasket which has a good handling property as a gasket used for a fuel battery or a gasket for an HDD, can be easily integrated with the other end mounting member even in the case that the other end mounting member such as a separator or the like is a material having low strength or a thin plate, and has good mounting workability, a gasket is having a sheet-shaped gasket mounting member provided with a sticking function on one face, and a gasket main body made of a rubber-type elastic member integrated with the sheet-shaped gasket mounting member, and the gasket is mounted to the other end mounting member on the basis of the sticking function of the sheet-shaped gasket mounting member.
摘要:
To effectively prevent deformation of an MEA and shift of GDLs, first GDLs, second GDLs, and separators are layered in order at both sides of the MEA in the thickness direction thereof, the gaskets which sandwich an end portion of the MEA outside the first GDLs and the second GDLs are made from rubber or a synthetic resin material having rubber-like elasticity and integrally provided on the separators respectively, the first GDLs have end portions which are formed so as to protrude beyond outer peripheries of the second GDLs, and the gaskets have support step portions which can position and support the end portions of the first GDLs at the same height as the support height by the second GDLs.
摘要:
A fuel cell sealing structure has a power generating body, and first and second separators arranged in both sides in a thickness direction of the power generating body. On a surface in one side in a thickness direction of the first separator, formed integrally first and second sealing protrusions respectively brought into close contact with an outer peripheral portion of the power generating body and the second separator in an outer peripheral side of the first sealing protrusion, and a short circuit prevention rib protruding in line with the first and second sealing protrusions by an electrically insulating rubber-like elastic material. On a surface in another side thereof, formed integrally a third sealing protrusion brought into close contact with a surface in an opposite side to the power generating body in the second separator, by the electrically insulating rubber-like elastic material.
