<p>Disclosed is a method for detecting a nucleic acid target sequence by formation of triple helix nucleic acid structures. The method may, but need not, involve amplifying the nucleic acid in vitro using cycles of denaturation and amplification to yield product duplexes, and detecting the product duplexes by hybridizing a third strand of nucleic acid to the product duplexes without denaturation. The triple helix-forming duplex sequences may be endogenous to the target sequence being detected, or they may be introduced in the probes used during amplification.</p> |
