The present invention provides a method of detecting (e.g., by flow cytometry) a target compound, cell or particle, wherein the target is labelled with a detectable luminescent compound. The method comprises utilizing as the detectable luminescent compound a compound comprising a porphyrinic macrocycle such as a porphyrin, chlorin, bacteriochlorin, or isobacteriochlorin. In particular embodiments, the detectable luminescent compound comprises a compound of the formula A-A′-Z-B′—B, wherein: A is a targeting group or member of a specific binding pair that specifically binds the detectable luminescent compound to the target compound, cell or particle; A′ is a linker group or covalent bond; B′ is a linker group or covalent bond; B is a water-soluble group; and Z is the porphyrinic macrocycle.
本发明提供了一种检测目标化合物、细胞或颗粒(例如,通过流式细胞术检测)的方法,其中目标标记有可检测的发光化合物。该方法包括使用一种包含卟啉宏环(例如卟啉、叶绿素、细菌叶绿素或异细菌叶绿素)的化合物作为可检测的发光化合物。在特定实施方式中,可检测的发光化合物包括式A-A'-Z-B'-B的化合物,其中:A是一个靶向基团或特异性结合对的成员,能够将可检测的发光化合物特异性地结合到目标化合物、细胞或颗粒上;A'是一个连接基团或共价键;B'是一个连接基团或共价键;B是一个水溶性基团;而Z是卟啉宏环。
