Botulinum Toxin
FDA ApprovedNeurotoxic protein / zinc-dependent endopeptidase
Botulinum Toxin is a potent neurotoxin produced by Clostridium botulinum that has been studied in neuroscience research for its effects on neuromuscular junction signaling. It has been investigated for its mechanism of action involving SNAP-25 protein cleavage and acetylcholine release inhibition. Published research has examined its receptor binding and intracellular trafficking. RaysunPeptide supplies Botulinum Toxin for qualified research and laboratory applications.
Mechanism of Action
The heavy chain binds presynaptic cholinergic nerve terminals and mediates internalization. The light-chain protease cleaves SNAP-25, disrupting synaptic vesicle fusion and inhibiting acetylcholine release.
Key Benefits

FAQs
Is botulinum toxin a peptide?
Not in the usual sense. Botulinum neurotoxin type A is a large bacterial protein of approximately 150 kDa consisting of a light chain and heavy chain.
How does botulinum toxin work?
Its light-chain protease cleaves SNAP-25 and prevents normal acetylcholine release from presynaptic nerve terminals.
