  • Relevance
    Clostridium botulinum neurotoxins are zinc-dependent proteases that block the release of acetylcholine from peripheral cholinergic nerve endings by targeting specific membrane proteins including synaptosomal-associated proteins (SNAP), vesicle-associated membrane proteins (VAMP), and syntaxins. Neurotoxin A is characteristically associated with human botulism and known to target and hydrolyse the 197-Gln-|-Arg-198 bond of SNAP-25.

For catalog # ab20641 and ab20786 a direct ELISA was performed. The limit of detection (LOD) with direct ELISA is greater than 1:10,000 on both products with no amplification using OPD (o-phenylenediamine dihydrochloride) development and HRP conjugated 2nd antibody.
This is the most detail that we have available, and we recommend optimization of the reagents/antibodies in your specific application.

Thank you for your enquiry. I can confirm that the immunogen for this antibody (ab20641) has not changed. A toxoid is an attenuated/inactivated toxin. The Clostridium botulinum Type A Neurotoxin is inactivated using formaldehyde before it is used as an immunogen to create this antibody. Fairly recently, a decision was taken to change toxin to toxoid on the datasheet as this was considered to be a more accurate description. I hope this information is helpful. Please do not hesitate to contact us again should you have any further questions.
