摘要:
The present invention is directed to multivalent Clostridial neurotoxin derivatives having more than one binding domain directed to a cell surface feature of a target cell. Such modified neurotoxins are useful as therapeutic compositions to prevent exocytosis and secretion by the target cell. Conditions in which such compositions man be useful include, without limitation, disorders of the sensory or motor nervous system, acute or chronic pain, cancer, pancreatitis, hyperhydrosis, glandular disorders, viral infections, cystic fibrosis and the like. The invention is also directed to methods of using and administering such a composition, and methods of treating a given condition using such a composition.

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.
