r-Saccharomyces Polypeptide-1 Hexapeptide-40 Hexapeptide-41 sh-Oligopeptide-1 is a single chain recombinant fusion peptide produced by fermentation in Saccharomyces. The starting gene is synthesized by the fusion of the gene from r-Saccharomyces Polypeptide-1, Hexapeptide-40, Hexapeptide-41 and sh-Oligopeptide-1. The fused peptide contains 90 amino acids and consists of the proper sequence of the 20 standard amino acids.
