Native Botulinum toxin is a high molecular weight complex, which, in addition to the neurotoxin (150 kD) contains other non-toxic proteins, like haemagglutinins and non- haemagglutinins.
Looduslik C. botulinum toksiin on kõrge molekulaarkaaluga kompleks, mis lisaks neurotoksiinile (150 kD) sisaldab ka teisi mittetoksilisi valke, nagu hemaglutiniinid ja mitte - hemaglutiniinid.
