  Lanthanide-Based Protease Activity Sensors for Time-Resolved Fluorescence Measurements

  摘要：

  Lanthanide-based luminescent sensors are noteworthy because their long-lifetime luminescence enables time-resolved fluorescence measurements. After exploring suitable antenna groups, we designed and synthesized lanthanide-based luminogenic sensors detecting protease activities. This sensor yielded strong luminescence on addition of proteases such as calpain I and leucine aminopeptidase (LAP). Since the luminescence lifetimes of the probes were very long, the sensors could be applied to time-resolved measurements that exclude background fluorescence signals derived from protiens or other impurities. This sensing principle could be applicable to general time-resolved fluorescence assays for other proteases.
