Methionyl sh-Oligopeptide-75 sh-Polypeptide-8 is a single chain synthetic fusion peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from sh-Oligopeptide-75 (q.v.) and sh-Polypeptide-8 (q.v.) with the initiation code for methionine. The fusion peptide contains 225 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids
