PBL offers a variety of procedures to assess the safety of therapeutic toxins such as botulinum toxin. These include potency assays, identity/safety testing, and Mouse Protection Assays (patient antibody testing). Testing is conducted in full compliance with CDC regulations and guidelines.
There are seven distinct variations of the neurotoxin, botulinum toxin, which is produced by the bacteria, Clostridium botulinum. The types that are approved for use in humans are forms A and B. Botulinum toxin A is approved for cosmetic use and botulinum toxin B is used for different types of muscle diseases.
Pacific BioLabs specializes in botulinum toxin testing for safety assessment, as well as other in vivo and in vitro bioassays.
