Botulinum toxin is a high-molecular-weight neurotoxin protein derived from Clostridium botulinum, studied in neuromuscular and neurophysiology research. It is supplied in sealed vials as a research-grade preparation for qualified laboratory applications. Botulinum toxin is investigated in research on neurotransmitter release, synaptic function and muscle-nerve interactions. This material is intended for qualified research use only and requires appropriate laboratory handling. Every batch is quality-controlled to ensure reliable performance for controlled experimental studies. Every batch undergoes strict quality control, and a Certificate of Analysis (COA) is available for specific batches upon request to support reproducible laboratory work. For storage, keep the unopened reagent sealed at 2-8 degree C and protected from light and moisture; for long-term storage, store at -20 degree C and avoid repeated freeze-thaw cycles. We support both small trial orders and large-volume bulk orders. OEM and private-label packaging services are available for research projects, and secure neutral packing is used for all shipments with worldwide delivery to the USA, Europe, Canada, Australia, the UK and many other regions. Please note that this product is intended for laboratory research use only and is not for human or veterinary application.
