Zusammenfassung:	Compositions for the multiplexed detection of the binding of, or interaction between, one or more ligands and target antiligands are provided. The compositions include one or more uncleaved or partially cleaved electrophoretic tag (e-tag) probes from a set of e-tag probes, at least one e-tag reporter out of a possible set of e-tag reporters and a capture agent. Detection involves the release of identifying tags as a consequence of target recognition. The e-tag probes comprise a detection region and a mobility-defining region called the mobility modifier, both linked to a target-binding moiety. Target antiligands are contacted with a set of e-tag probes and the contacted antiligands are treated with a selected cleaving agent resulting in a mixture of e-tag reporters and uncleaved and/or partially cleaved e-tag probes. The mixture is exposed to a capture agent effective to bind to uncleaved or partially cleaved e-tag probes, followed by electrophoretic separation. In a multiplexed assay, different released e-tag reporters may be separated and detected providing for target identification.
