Description: Botulinum neurotoxin type B (BoNT/B) is produced by Clostridium botulinum, a genetically diverse class of anaerobic, spore-forming, gram-positive bacilli. Seven different botulinum toxin groups have been identified serologically and are called botulinum toxin type A,B,C1,D,E,F, and G (1). BoNT/B is a two-chain polypeptide with a 100-kDa heavy chain, which is responsible for neurospecific binding joined by a disulphide bond to a 50-kDa light chain, a zinc-endopeptidase which blocks neurotransmitter release (2,3). BoNT/B is one of the most poisonous naturally occurring substances. It inhibits acetylcholine release from neuromuscular junctions while it is used as an important therapeutic mainstay in the treatment of spasticity disorders and as a cosmetic treatment (4).

FACS analysis of BOSC23 cells using GR-3G7. BOSC23 cells were transiently trans-fected with an expression vector encoding eitherBoNT/B(red curve) or an irrelevant protein (controltransfectant). Binding of GR-3G7 was detected with a PE conjugated secondary antibody. A positive signal was obtained only with BoNT/B transfected cells.

BOSC23 cells were transiently transfected withexpression vectors containing the cDNA of the lightchain of botulinum toxin A-F. Expression of the constructs was tested with an anti-myc antibody (greencurves). An irrelevant monoclonal antibody served as an
