| 摘要 |
Compositions of nucleic acid hybridization probes for detecting a nucleic acid target sequence and methods for their production are described. In one preferred embodiment, the nucleic acid hybridization probe includes a hybridization domain, an adaptor, a linker, and a signaling domain. The hybridization domain includes a nucleic acid sequence having complementarity to the nucleic acid target sequence. The adaptor is a nucleic acid sequence. The linker includes a moiety having at least one abasic site, such that the moiety blocks extension by an elongating polymerase on a nucleic acid template containing the moiety. The signaling domain comprises a nucleic acid having at least one label or a nucleic acid having at least one nucleic acid domain for binding at least one additional nucleic acid. |
