1. A method for multiplexing the detection of a target molecule comprising:
- (a) obtaining a plurality of probes, each comprising a reactive group, a release group and a mass label comprising a biopolymer;
(b) contacting the target molecule with the plurality of probes to produce probe;
target molecule complexes, wherein the target molecule is attached to the reactive group of the probe;
(c) releasing the mass labels from the probe;
target molecule complexes to produce released mass labels; and
(d) determining the mass of the released mass labels by mass spectrometry, whereineach reactive group in a probe;
target molecule complex is associated with a unique set of mass labels.
