Abstract:
1. A composition comprising a plurality of solid-phase assay reagents each said reagent selectively active in an assay for a single analyte relative to a plurality of assays for different analytes, each said solid-phase assay reagent comprising a binding species that is selectively active in a single assay relative to said plurality of assays and coupled to one of a plurality of microparticles of magnetically responsive material, the microparticles coupled to each binding species being distinguishable from magnetically responsive microparticles coupled to other binding species by two or more parameters that are detectable by flow cytometry and by the binding species coupled thereto, said microparticles being suitable for use in a multiplex assay procedure that includes the use of flow cytometry.
