Assays of molecular or subcellular proximity using depolarization after resonance energy transfer (DARET)

摘要

The present invention provides a method of determining the proximity, or changes in the proximity of two or more molecular features labeled with fluorophores able to undergo DARET. In preferred embodiments the change in proximity of molecular features in a sample is correlated with changes in the fluorescence polarization of the sample, and may be monitored in real time.
