摘要： The present invention provides a method of determining the presence or activity of a clostridial toxin by (a) treating with a sample, under conditions suitable for clostridial toxin protease activity, a clostridial toxin substrate which includes a fluorophore; a bulking group; and a clostridial toxin recognition sequence containing a cleavage site that intervenes between the fluorophore and the bulking group; (b) exciting the fluorophore with plane polarized light; and (c) determining fluorescence polarization of the treated substrate relative to a control substrate, where a change in fluorescence polarization of the treated substrate as compared to fluorescence polarization of the control substrate is indicative of the presence or activity of the clostridial toxin.

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.
