Thermo Scientific Pierce EDC is a carboxyl- and amine-reactive zero-length crosslinker. EDC reacts with a carboxyl group first and forms an amine-reactive O-acylisourea intermediate that quickly reacts with an amino group to form an amide bond with release of an isourea by-product. The intermediate is unstable in aqueous solutions and so two-step conjugation procedures rely on N-hydroxysuccinimide (NHS) for stabilization. Failure to react with an amine will result in hydrolysis of the intermediate, regeneration of the carboxyl, and release of an N-substituted urea. A side reaction is the formation of an N-acylurea, which is usually restricted to carboxyls located in hydrophobic regions of proteins.

The potent toxicity of both the botulinum neurotoxins and anthrax lethal toxin is due to a zinc-dependent proteolytic activity associated with the toxins.  Measurement of this enzymatic activity provides for both a potentially sensitive and direct means for detection of the toxin, and a method for identifying potential toxin inhibitors using high throughput screening. A highly efficient approach for monitoring enzymatic activity is based on the use of fluorescence resonance energy transfer (FRET) substrates. These fluorogenic peptides contain a donor fluorescent group at one end and a suitable chromogenic acceptor group at the other.  The fluorescence is quenched initially by intramolecular energy transfer between the donor/acceptor pair.  Cleavage of the FRET substrate by the appropriate enzyme releases the fluorophore and full fluorescence is restored.  The increase in fluorescence intensity is directly proportional to the amount of enzyme present.  Enzymatic activity can be monitored continuously by recording the increase in fluorescence intensity with time.  The change in the relative fluorescence units (RFU) as cleavage occurs can be converted to nmoles of cleaved substrate from a standard curve generated using a Calibration Peptide which is the cleaved substrate containing only the N-terminally attached fluorophore.  For Botulinum neurotoxin type A, a Control FRET peptide substrate that is not cleaved by the neurotoxin but contains all remaining non-specific sites in the sequence can be used to screen background cleavage of the substrate that can occur in complex matrices.
