摘要：

Quenching of fluoresence in water of fluorescent rare earth chelates is avoided by incorporating them into the hydrophobic phase of a loadable polymeric latex. The aqueous stabilized fluorescent labels so formed may be used to label proteins, antigens, antibodies or enzymes which may be used in immunoassay analytical processes. The fluorescent labelled antigens and antibodies are particularly suited to temporal resolution fluoresence measurement techniques.
