Ethyl Carbazido Hyaluronate sh-Oligopeptide-1 sh-Polypeptide-94 Dipeptide-35 sh-Polypeptide-94 sh-Polypeptide-95 is a single chain recombinant fusion peptide, produced by fermentation in Chinese hamster ovary cells (CHO). The starting gene is synthesized by the fusion of the gene from sh-Oligopeptide-1, sh-Polypeptide-94, Dipeptide-35, and sh-Polypeptide-95. The fusion peptide is conjugated with ethyl carbazido hyaluronate, and it consists of the proper sequence of the 20 standard amino acids.
