PROCESS FOR THE DEMONSTRATION AND DETERMINATION OF REACTION COMPONENTS HAVING SPECIFIC BINDING AFFINITY FOR EACH OTHER
First Claim
2. Process for the demonstration and determination of a component of the reaction between a bindable substance selected from the group consisting of an antigen, a hapten, and a low molecular substance, and a protein capable of binding said bindable substance specifically, said protein being selected from the group consisting of an antibody and a specific binding protein, comprising the steps of:
- a. providing a given quantity of the binding partner of the component to be determined in a soluble form;
b. adding a given quantity of an antibody against said binding partner, which antibody is in an insoluble form, to form a reaction mixture having a solid phase and a liquid phase;
c. separating the solid phase from the liquid phase;
d. adding to said solid phase a given quantity of a coupling product of the component to be determined with an enzyme; and
e. determining the enzyme activity of either the liquid phase or the solid phase, which activity is a measure of the quantity of the reaction component to be determined.

Abstract
The present invention relates to a process for the determination of a component of the reaction between a specific binding protein and the substance being specifically bound by such a protein comprising reacting the component to be determined with its binding partner in an insolubilized form, separating the solid phase of the reaction mixture from the liquid phase, reacting the solid phase with a determined amount of a coupling product of the substance to be determined with an enzyme, and finally determining the enzyme activity of the liquid or solid phase of the reaction mixture obtained.
