Method for carrying out an immunoassay in a multiphase system

The present invention relates to a method of carrying out an immunoassay in a multiphase system. A sample containing an analyte is brought into contact with a receptor A and a tracer. The analyte can either form a complex with the tracer, or counteract the formation of a complex of receptor A and tracer by competing with the tracer for binding to receptor A, or counteract the formation of a complex of receptor A and tracer by competing with receptor A. Receptor B is added and the signal is determined. In this method, receptor A and receptor B are suitably immobilized, ensuring that the tracer either cannot enter into any binding involving the simultaneous participation of receptors A and B or can enter into such a binding to only such a slight extent that it is nevertheless possible to detect and differentiate differing analyte concentrations.

Competitive immunoassay using complexed analyte derivatives

The invention relates to a method for the detection of an analyte in a competitive immunoassay in the presence of an analyte derivative and first and second receptor molecules, and to a kit for carrying out this detection method.

Process for the stabilization of biologically active substances immobilized on solid phases

The invention relates to a process for the stabilization of biologically active substances which are immobilized on a carrier, where the solid phase with the immobilized biologically active substance is contacted for the stabilization with a solution which contains polyanetholesulfonic acid and/or salts thereof. The biologically active substances are, in particular, antibodies.

Homogeneous gene probe test using a receptor directed against the label

The invention relates to a homogeneous gene probe test, which is based on altering the signal of the nonhybridized gene probe by a receptor directed against the label.

Immunoassays for haptens and hapten tracer-antibody complex which can be used therefor, and process for the preparation thereof

There are disclosed hapten tracer complexes which, on the one hand, contain a hapten which is linked to an indicator component and, on the other hand, an antibody which can bind specifically to the indicator component. These hapten tracer complexes can be employed advantageously in immunoassays.

Method of carrying out an immuno-assay in a multi-phase system

The present invention relates to a method of carrying out an immunoassay in a multiphase system. A sample containing an analyte is brought into contact with a receptor A and a tracer. The analyte can either form a complex with the tracer, or counteract the formation of a complex of receptor A and tracer by competing with the tracer for binding to receptor A, or counteract the formation of a complex of receptor A and tracer by competing with receptor A. Receptor B is added and the signal is determined. In this method, receptor A and receptor B are suitably immobilized, ensuring that the tracer either cannot enter into any binding involving the simultaneous participation of receptors A and B or can enter into such a binding to only such a slight extent that it is nevertheless possible to detect and differentiate differing analyte concentrations.
