摘要:
A system and method for identifying a botulinum neurotoxin inhibitor employing a botulinum neurotoxin substrate complex having a peptide substrate, preferably SNAP-25, a reporter domain on one side of said peptide substrate and an immobilization domain on the opposite side of said peptide substrate. The botulinum neurotoxin inhibitor is identified by its ability to decrease the relative amount of cleaved complex, detected through measuring a decrease in complex bound to a solid support. The method of the present invention also utilizes novel cells that express a botulinum neurotoxin substrate complex. Also provided are novel stable cell lines that express the botulinum toxin substrate complex and viral vectors capable of efficiently expressing an active light chain of the BoNT within mammalian cells.
