r-(Oligopeptide-133 sh-Polypeptide-11) is a single chain fusion peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the genes encoding for Oligopeptide-133 and sh-Polypeptide-11. The fusion peptide contains 166 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids,
