Abstract
The invention provides a method for detecting a target analyte, by: (a) contacting one or more target analytes with a set of first and second binding reagents under conditions sufficient for binding of a target analyte with the first and second binding reagents, each of the first binding reagents containing a cleavage-inducing moiety and a target binding moiety, each of the second binding reagents containing a tagged probe having a mass modifier region attached to a target binding moiety by a cleavable linkage, the cleavable linkage being susceptible to cleavage when in proximity to an activated cleavage-inducing moiety; (b) activating the cleavage-inducing moiety to release a tag reporter, and (c) detecting a mass of the tag reporter, the mass uniquely corresponding to a known target analyte.
