Claim:
1. A kit for conducting a method of measuring a binding interaction comprising: multiple sets of microparticles, the microparticles of each set having an identifiable characteristic unique to each set such that each set is distinguishable from the other sets, wherein each set comprises at least two subsets of microparticles presenting a probe unique to each subset, wherein the probe of each subset binds to a different target molecule within a biological sample from the target molecule bound by other subsets, forming a binding complex with the target molecule; and a labeling reagent for labeling the binding complex with a detectable label that produces a measurable signal when a specific binding complex is present, and wherein the signal varies in intensity such that only the microparticles exhibiting greatest signal intensity, which comprises a proportion of less than 100% of the microparticles, are selected for analysis.
