Patent ID: 8313903

Claim:
A non-naturally occurring, noncatalytic oligonucleotide probe for detecting a single-stranded oligonucleotide analyte, comprising two oligonucleotide strands, wherein (1) a first oligonucleotide strand comprises: a. at its 5′-terminus a reporter binding arm that is complementary to and is capable of selectively hybridizing with a reporter, and b. at its 3′-terminus, a first analyte binding arm that is complementary to and is capable of selectively hybridizing with a first region of the oligonucleotide analyte, and (2) a second oligonucleotide strand comprises: a. at its 3′-terminus a reporter binding arm that is complementary to and is capable of selectively hybridizing with a nucleotide sequence in the reporter, and b. at its 5′-terminus, a second analyte binding arm that is complementary to and is capable of selectively hybridizing with a second region of the oligonucleotide analyte.
