Probes comprising one or more selectively cleavable α-azidoether moieties are provided; and linkers comprising the one or more selectively cleavable α-azidoether moieties. The α-azidoether moiety will undergo a Staudinger reaction with a suitable reducing agent, resulting in cleavage. The probes find use in a variety of detection assays, e.g. specific polynucleotide binding assays, polypeptide binding assays, etc. The cleavable linkers are suitable for synthetic reactions, e.g. to prepare probes of the invention; in the synthesis of cleavable peptide conjugates; and the like.

RNA-templated fluorescence activation is a nucleic acid detection strategy that offers the possibility of direct visual detection of genetic information in living cells. Here we describe a new reaction strategy for fluorescence activation in which a phosphine on one DNA probe reduces an azide group in a linker on a second probe, resulting in linker cleavage and release of a fluorescence quenching group. These "Q-STAR" probes are shown to yield a strong fluorescence turn-on signal in similar to 20 min, with very tow background and substantial amplification by turnover on the template. A green/red pair of such probes allowed the discrimination of two bacterial species by a single nucleotide difference in their 16S rRNA. The beneficial properties of the reductive quencher release design make these probes promising candidates for widespread application in the detection of nucleic acids in vitro and in cells.
