    摘要: The present invention provides a method of determining clostridial toxin activity by (a) contacting with a sample a cell containing a clostridial toxin substrate that includes a donor fluorophore; an acceptor having an absorbance spectrum overlapping the emission spectrum of the donor fluorophore; and a clostridial toxin recognition sequence containing a cleavage site that intervenes between the donor fluorophore and the acceptor, where resonance energy transfer is exhibited between the donor fluorophore and the acceptor under the appropriate conditions; (b) exciting the donor fluorophore; and (c) determining resonance energy transfer of the contacted cell relative to a control cell, where a difference in resonance energy transfer of the contacted cell as compared to the control cell is indicative of clostridial toxin activity.

    摘要: Natural and modified neurotoxins and isolated neurotoxin compositions are described. The neurotoxins may include one or more structural modifications, wherein the structural modification(s) alters the biological persistence, such as the biological half-life and/or a biological activity of the modified neurotoxin relative to an identical neurotoxin without the structural modification(s). In one embodiment, methods of making the modified neurotoxin include using recombinant techniques. In another embodiment, methods of using the modified neurotoxin to treat conditions include treating various disorders, neuromuscular aliments and pain.
