Located in the University of Wisconsin Research Park in Madison, Wisconsin, USA, Metabiologics, Inc. is currently manufacturing and selling all seven serotypes of botulinum toxin for use by accredited researchers on a worldwide basis. Metabiologics manufactures toxin products to the highest industry standard for purity and specific activity. Customized product specifications and order quantities are available upon request. Antibodies to botulinum toxins are also available.



Botulinum neurotoxin is produced by the bacterium Clostridium botulinum. The neurotoxin produces a dose-related weakness of skeletal muscle by impairing the release of acetylcholine at the neuromuscular junction. There are at least seven immunologically distinct forms of botulinum neurotoxin, designated as serotypes A-G. Type A neurotoxin is the most commonly used for human use.

Metabiologics was founded in 1999 by scientists from the University of Wisconsin Food Research Institute, who have been conducting botulinum neurotoxin research since the 1980's. Botulinum neurotoxins’ high profile as a food contaminant comes from the neurotoxins’ ability to weaken skeletal muscles to such an extent that it can cause partial paralysis and result in respiratory failure. During the 1990's, notable improvements in the development and manufacturing of research grade botulinum neurotoxin were made, and Metabiologics was born.

Metabiologics is committed to the production of high quality reagent grade products. Researchers and corporate entities are encouraged to contact us regarding potential experimental collaborations.
