Abstract:
A composition of matter comprising:(a) a plurality of different ligand analogue conjugates each different ligand analogue conjugate corresponding to a one of a plurality of different target ligands, wherein each ligand analogue conjugate comprises a binding site for an antibody or a ligand receptor produced by a standard immunologic technique, and wherein each ligand analogue conjugate is attached via a linkage site to a protein, polypeptide, polymer, or a signal development element, said linkage site being the same or different from the linkage site of the other ligand analogue conjugates; and (b) at least one crosstalk inhibitor comprising an analogue of at least one linkage site present amongst the plurality of different ligand analogue conjugates, wherein the crosstalk inhibitor is present in an amount sufficient to inhibit binding of the linkage site of at least one ligand analogue conjugate in a ligand receptor assay to an antibody or ligand receptor produced by a standard immunologic technique.
