摘要:
A chimeric toxin is disclosed comprising a peptide ligand specifically targeting neurons involved in pain processing; and a clostridial neurotoxin light chain, wherein the ligand is linked to the light chain. The methods of preparing such chimeric toxin and the method of using the chimeric toxin to regulate pain transmission are also disclosed.
摘要:
The present invention provides a novel isolated plasmid, wherein the plasmid is a native plasmid found in unique C. botulinum type A strains and encode either BoNT/A3 or BoNT/A4 and BoNT/B. The present invention also provides a method of obtaining a plasmid-encoded botulinum neurotoxin and botulinum neurotoxin complex comprising the step of isolating a plasmid encoding the cntA/A or cntA/B neurotoxin gene and genes encoding protein components of the toxin complex from a C. botulinum type A strain. The inventors performed comparative analyzes of representative BoNT/A subtype strains by pulsed-field gel electrophoresis (PFGE) and Southern hybridizations with probes specific for the BoNT/A and B genes, cntA/A and cntA/B. Unexpectedly, the inventors determined that the genes encoding BoNT/A3 in the A3 strain, and BoNT/A4 and BoNT/B in the A4 strain, are on plasmids.

摘要:
A method of producing botulinum toxin C-terminal receptor binding domain (HCR) is disclosed. The one embodiment, the method comprises the steps of (a) preparing E. coli transformed with an expression vector comprising DNA encoding HCR protein, (b) inducing expression of the HCR protein at a reduced temperature in a culture media, and (c) purifying the HCR protein via extraction, wherein the extraction comprises a clarification by centrifugation and a filtration, wherein the purified HCR protein is at least 10 mg/L of culture medium.
