Functional fluorescence assay of botulinum neurotoxin A in complex matrices using magnetic beads

The extremely toxic botulinum neurotoxin poses a threat for health and food safety, requiring rapid and easy-to-use detection platforms. To meet these requirements, we have explored a novel functional assay format for detection of botulinum neurotoxin serotype A light chain (BoNT/A LC) in complex matrices. The proposed assay utilizes a synthetic peptide designed to mimic the SNAP-25 protein (synaptosomal-associated protein 25) as substrate bound...
