sr-(Oligopeptide-184 Clostridium Botulinum Polypeptide-1) is a single chain recombinant peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the genes from Oligopeptide-184 and s-Clostridium Botulinum Polypeptide-1. The fusion peptide contains 476 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.

sr-(Oligopeptide-188 sh-Oligopeptide-1) is a single chain fusion peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from Oligopeptide-188 and sh-Oligopeptide-1. The fusion peptide contains 82 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.

sr-(Oligopeptide-188 sh-Polypeptide-1) is a single chain fusion peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from Oligopeptide-188 and sh-Polypeptide-1. The fusion peptide contains 183 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids

sr-(Clostridium Botulinum Polypeptide-1 Oligopeptide-192 Clostridium Botulinum Polypeptide-1 Oligopeptide-192 Oligopeptide-193) is a single chain recombinant peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from sr-Clostridium Botulinum Polypeptide-1, Oligopeptide-192 and Oligopeptide-193. The fusion peptide contains 507 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
