    Product Description

     

    Botulinum and tetanus neurotoxins (BoNTs and TeNT) are zinc metalloproteases that hydrolyze and inactivate proteins necessary for neurotransmission. The protease domain is located in the light chain of the neurotoxin. Among the known substrates of BoNTs and TeNT are synaptosomal protein-25 (SNAP25) and vesicle-associated membrane protein (VAMP). This substrate incorporates a green fluorescent protein (GFPuv) and portions of human SNAP25B and VAMP2 that contain the cleavage sites of all the known BoNTs and TeNT. The light chains of BoNTs -A, -C, and -E cleave the SNAP25B sequence, while BoNTs -B, -D, -F, -G, and TeNT cleave within the VAMP2 sequence. The substrate can be used in a SDSPAGE gel-shift assay to detect cleavage by the neurotoxin proteases. Alternatively, the substrate can be coupled to maleimide-activated microwell plates through the C-terminal cysteine residue to generate a high throughput assay format. A similar substrate and assay format has been used to screen for inhibitors of these neurotoxin proteases.

    Formulation

    Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions

     

    Avoid repeated freeze-thaw cycles.

    For your safety and health, please wear lab coats and disposable gloves for operation.
