| 摘要 |
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. |
