      Description
      OverviewA synthetic peptide, fluorescence resonance energy transfer (FRET) substrate containing the N-terminally-linked fluorophore o-aminobenzoic acid (Abz) and the acceptor chromophore 2,4-dinitrophenol (DNP) linked to the C-terminus. The substrate is based on the native botulinum toxin type A cleavage site found in the synaptosome-associated protein SNAP-25. Cleavage of the substrate by botulinum toxin releases the fluorophore and full fluorescence is restored.

      Recommended reaction conditionsThe FRET assays are performed using HEPES buffers prepared by titrating the free acid form of HEPES with the potassium salt form of HEPES. For assays with BoNT/A, the SNAPtide® stock solution is diluted using 20 mM HEPES, pH 8.0, prior to use. For assays with BoNT/A Light Chain, the stock solution should be diluted in the hydrolysis buffer, described in the section below. When using a 96-well plate and a final volume of 250 µl/well, a 250 µM stock solution is convenient to use. The final concentration of SNAPtide® to be used is typically between 5 µM and 10 µM/well, depending on the instrumentation and experiment. Since DMSO inhibits cleavage, final concentrations must be less than 2% of the total volume. For SNAPtide® (o-Abz/Dnp any concentration of ZnCl2 in the BoNT/A Light Chain hydrolysis buffer inhibits cleavage.

      These FRET assays are run at 37°C. Excitation wavelength is 320 nm and emission is 420 nm. There is a linear dependence of fluorescence intensity on concentration of totally cleaved substrate up to 30 ~M SNAPtide®(o-Abz/Dnp). When measuring kinetic parameters such as the Km and Vmax for this FRET substrate, the data must be corrected for a phenomenon known as the "inner filter effect". This effect, as well as a method to determine an appropriate correction factor, is explained in the paper by Liu, et al. 1999. Analytical Biochemistry 267, 331. The correction method uses an unquenched fluorophore for comparison.
