sr-(Clostridium Botulinum Polypeptide-1 Decapeptide-84 HIV-1 Oligopeptide-8 Glutamine) is a single chain recombinant peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from r-Clostridium Botulinum Polypeptide-1, sr-Decapeptide-84, and s-HIV-1 Oligopeptide-8. The fusion peptide contains 470 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
