Abstract

Abstract Immunochemical measurement by either (1) the reaction of the measurement substance with the insolubilized substance and then the reaction of the reaction product of the first procedure with the labeled substance or (2) the reaction of the measurement substance with the labelled substance and then the reaction of the resulting reaction product with the insolubilized substance, or (3) the simultaneous reaction of the three substances.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 164 words
An immunochemical measuring process comprising the steps of (a) mixing and reacting a substance to be measured with a given amount of an insolubilized substance which is obtained by insolubilizing a substance specifically bindable with the substance to be measured, (b) without separating the bound product comprising the substance to be measured and the insolubilized substance from the reaction mixture, reacting the reaction product produced in the step (a) with a given amount of a labelled substance which is obtained by labelling a substance specifically bindable with the substance to be measured with a labelling agent, (c) separating the reaction product produced in step (b) into an insoluble reaction product which is the solid phase containing the labelled substance which is bound to the insolubilized substance, and a liquid reaction product which is liquid phase, containing the unbound labelled substance, and (d) measuring the activity of either the labelled substance bound with said solid phase or the labelled substance existing in the liquid phase.
Claim 2
Dependent Claim 164 words
An immunochemical measuring process comprising the steps of (a) mixing and reacting a substance to be measured with a given amount of an insolubilized substance which is obtained by insolubilizing a substance specifically bindable with the substance to be measured, (b) without separating the bound product comprising the substance to be measured and the insolubilized substance from the reaction mixture, reacting the reaction product produced in the step (a) with a given amount of a labelled substance which is obtained by labelling a substance specifically bindable with the substance to be measured with a labelling agent, (c) separating the reaction product produced in step (b) into an insoluble reaction product which is the solid phase containing the labelled substance which is bound to the insolubilized substance, and a liquid reaction product which is liquid phase, containing the unbound labelled substance, and (d) measuring the activity of either the labelled substance bound with said solid phase or the labelled substance existing in the liquid phase.
Claim 3
Dependent Claim 119 words
An immunochemical measuring process comprising the steps of (a) mixing and reacting a substance to be measured with a given amount of a labelled substance which is obtained by labelling a substance specifically bindable with the substance to be measured with a labelling agent, (b) reacting the reaction mixture produced with a given amount of an insolubilized substance which is obtained by insolubilizing a substance specifically bindable with the substance to be measured, (c) separating the reaction product produced in the step (b) into an insoluble product (solid phase) and a liquid product (liquid phase), and (d) measuring the activity of either the labelled substance bound with the solid phase or the labelled substance existing in the liquid phase.
Claim 4
Dependent Claim 119 words
An immunochemical measuring process comprising the steps of (a) mixing and reacting a substance to be measured with a given amount of a labelled substance which is obtained by labelling a substance specifically bindable with the substance to be measured with a labelling agent, (b) reacting the reaction mixture produced with a given amount of an insolubilized substance which is obtained by insolubilizing a substance specifically bindable with the substance to be measured, (c) separating the reaction product produced in the step (b) into an insoluble product (solid phase) and a liquid product (liquid phase), and (d) measuring the activity of either the labelled substance bound with the solid phase or the labelled substance existing in the liquid phase.
Claim 5
Dependent Claim 17 words
The immunochemical measuring process of claim 2, wherein the steps (a) and (b) are simultaneously carried out.
Claim 6
Dependent Claim 23 words
Immunochemical measuring process of claim 1, wherein the substances to be measured include antigenic substances, haptens, antibodies and physiologically active peptides and amines.
Claim 7
Dependent Claim 23 words
Immunochemical measuring process of claim 2, wherein the substance to be measured include antigenic substances, haptens, antibodies and physiologically active peptides and amines.
Claim 8
Dependent Claim 23 words
Immunochemical measuring process of claim 3, wherein the substances to be measured include antigenic substances, haptens, antibodies and physiologically active peptides and amines.
Claim 9
Dependent Claim 20 words
Immunochemical measuring process of claim 1, wherein the insolubilized substance is a bindable substance insolubilized by binding to a carrier.
Claim 10
Dependent Claim 20 words
Immunochemical measuring process of claim 2, wherein the insolubilized substance is a bindable substance insolubilized by binding to a carrier.
Claim 11
Dependent Claim 20 words
Immunochemical measuring process of claim 3, wherein the insolubilized substance is a bindable substance insolubilized by binding to a carrier.
Claim 12
Dependent Claim 16 words
Immunochemical measuring process of claim 1, wherein the labeling agent is radioisotope, enzyme or fluorescent material.
Claim 13
Dependent Claim 16 words
Immunochemical measuring process of claim 2, wherein the labeling agent is radioisotope, enzyme or fluorescent material.
Claim 14
Dependent Claim 16 words
Immunochemical measuring process of claim 3, wherein the labeling agent is radioisotope, enzyme or fluorescent material.
