Abstract
Novel conjugates and competitive and non-competitive assays for simultaneously detecting the presence or amount of at least two target ligands capable of competing with a single conjugate for binding to at least two different ligand receptors. The invention teaches and claims binding domains coupled to a signal development element to form a conjugate where each binding domain comprises at least one ligand analogue or ligand receptor depending on assay design. The binding domains are constructed such that they function independently from one another in assays for their respective target ligands. Each binding domain may bind its respective binding partners in the assay without affecting the binding reactions of other binding domains coupled to the same signal development element.
