Oligo-(sh-Polypeptide-47) is a single chain recombinant human peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of repeats of the gene from sh-Polypeptide-47. The fusion peptide contains 780 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
