描述

一般說明

A 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.
