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.
提供了包含一个或多个可选择性裂解的α-
叠氮醚基团的探针;以及包含一个或多个可选择性裂解的α-
叠氮醚基团的连接体。α-
叠氮醚基团将与合适的还原剂发生斯陶丁格反应,导致裂解。这些探针适用于各种检测分析中,例如特定的多核苷酸结合分析、
多肽结合分析等。可裂解的连接体适用于合成反应,例如制备本发明的探针;在裂解肽共轭物的合成中使用等。
