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.
本发明提供了包含一种或多种可选择性断裂的α-
叠氮醚基团的探针;以及包含一种或多种可选择性断裂的α-
叠氮醚基团的连接物。α-
叠氮醚基团将通过与适当的还原剂发生斯陶德格反应而发生断裂。这些探针可用于各种检测测定中,例如特定的多
核苷酸结合测定、
多肽结合测定等。可断裂的连接物适用于合成反应,例如制备本发明的探针;合成可断裂的肽共轭物等。
