Abstract:
1. A method of analyzing a sample of nucleic acids, the method comprising: providing a plurality of probe molecules wherein the plurality comprises at least one probe molecule for each target nucleic acid sequence to be analyzed, the probe molecule comprising a region of sequence substantially complementary to a sequence in the target nucleic acid sequence and an internal capture tag sequence that is internal to a nucleic acid strand of said probe molecule; contacting the plurality of probe molecules to a sample of nucleic acids under conditions that allow a set of probe molecules for which a complementary sequence is present among the nucleic acids of the sample, to hybridize to the respective complementary sequence; cleaving the probes molecules of the set, wherein the cleavage is specific for the probe molecules that hybridize to nucleic acids of the sample and the cleavage positions the capture tag sequence of each cleaved probe molecule at a terminus of the cleaved probe molecule; and detecting one or more of the cleaved probes by hybridizing the tag sequences to capture probes disposed on a substrate, thereby analyzing the sample of nucleic acids.
