… Next, 25 μL of 200 μM SNAPtide 520 (List Biological Laboratories Inc., Campbell, CA, USA) was added to each reaction tube (equivalent to 13.3 μM SNAPtide 520) followed by incubation at 30 °C for 20 h (digestion step). Reactions were quenched following the addition of 25 μL of 5% trifluoroacetic acid (TFA). The contents of each tube were then transferred to HPLC vials for analysis. The fluorescently-labeled cleavage product(s) were separated and detected via a reverse-phase (RP)-HPLC method [28] using a Waters 2695 XE Separations Module and a Waters 2475 Multi λ Fluorescence Detector (Waters Corp., Milford, MA, USA). In brief, 25 µL of cleavage products were loaded onto a Symmetry C18 column (300 Å, 3.5 µm, 4.6 mm × 150 mm; Waters Corp.), maintained at 35 °C. Separation was accomplished using a 10−90% CH3CN (0.1% TFA) gradient for 30 min, with a flow-rate of 1 mL/min. The column effluent was monitored fluorescently (excitation λ = 322 nm, emission λ = 420 nm) to detect the o-aminobenzoic acid fluorophore on the N-terminal cleaved fragment of SNAPtide 520. SNAPtide cleavage product (#529, List Biological Laboratories, Inc.) was utilized to identify retention time of the cleavage product, as #529 is the unquenched calibration peptide for SNAPtide 520 substrate for C. botulinum type A neurotoxin.
