摘要： A method and kit for detecting a target nucleic acid in a sample is described. The sample to be analyzed may include a primer which hybridizes to at least a portion of the target nucleic acid, a probe having a first region which hybridizes to at least a portion of the target nucleic acid and a second region having a detectable label, a polymerase which extends the hybridized primer and an enzyme comprising exonuclease activity that can cleave the hybridized hybridization probe to thereby generate a labeled probe fragment. At least one portion of the hybridization probe hybridizes to another portion of the hybridization probe to thereby form a folded structure. The method can involve melting the sample, reducing the temperature of the sample to allow primer and probe to each hybridize to at least a portion of single stranded target nucleic acid in the sample, elongating the primer and releasing the labeled probe fragment. The sample can be contacted with a solid support comprising surface bound capture probes which hybridize to the labeled probe fragments. The label can then be detected.

These capture probes more readily bind to the probe fragment(s) than to the intact hybridization probe. The label can then be detected on the support surface. In this manner, improved discrimination between the probe fragments and the intact hybridization probes can be achieved.

摘要： Methods for detecting a target polynucleotide sequences are provided that utilize a probe having a target-complementary segment and a detectable tag. By cleaving the detectable tab and associating the tag with a tag complement coupled to an electrode, an electrochemical signal can be detected that is related to the presence of the tag:tag complement complex.
